An Analytically Enriched Finite Element Method for Cohesive Crack Modeling
Thu, Apr 29, 2010 @ 10:00 AM - 11:00 AM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. James V. Cox, Soild Mechanics Department, Sandia National Laboratories, Albuquerque, NM 87185-0346jvcox@sandia.govAbstract:Meaningful computational investigations of many solid mechanics problems require accurate characterization of material behavior through failure. A recent approach to fracture modeling has combined the partition of unity finite element method (PUFEM) with cohesive zone models. Extension of the PUFEM to address crack propagation is often referred to as the extended finite element method (XFEM). In the PUFEM, the displacement field is enriched to improve the local approximation. Most XFEM studies have used simplified enrichment functions (e.g., generalized Heaviside functions) to represent the strong discontinuity but have lacked an analytical basis to represent the displacement gradients in the vicinity of the cohesive crack. As such, the mesh had to be sufficiently fine for the FEM basis functions to capture these gradients.In this study enrichment functions based upon two analytical investigations of the cohesive crack problem are examined. These functions have the potential of representing displacement gradients in the vicinity of the cohesive crack with a relatively coarse mesh and allow the crack to incrementally advance across each element. Key aspects of the corresponding numerical formulation are summarized. Analysis results for simple model problems are presented to evaluate if quasi-static crack propagation can be accurately followed with the proposed formulation. A standard finite element solution with interface elements is used to provide the accurate reference solution, so the model problems are limited to a straight, mode I crack in plane stress. Except for the cohesive zone, the material model for the problems is homogenous, isotropic linear elasticity. The effects of mesh refinement, mesh orientation, and enrichment schemes that enrich a larger region around the cohesive crack are considered in the study. Propagation of the cohesive zone tip and crack tip, time variation of the cohesive zone length, and crack profiles are presented. The analysis results indicate that the enrichment functions based upon the asymptotic solutions can accurately track the cohesive crack propagation independent of mesh orientation. Example problems incorporating enrichment functions for mode II kinematics are also presented. The results yield acceptable crack paths compared with experimental studies. The applicability of the enrichment functions to problems with anisotropy, large strains, and inelasticity is the subject of ongoing studies. Preliminary results for a contrived orthotropic elastic material reflect a decrease in accuracy with increased orthotropy but do not preclude their application to this class of problems

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Tingye Li,
Formerly of AT&T LabsRefreshments will be providedAbstract: Strategic research may be regarded as work that is focused on producing viable advances and innovations in a particular field. It can be fundamental or applied, but always involves having realistic goals in mind, an understanding of physics and limitations, and an appreciation for application issues. It is often associated with a vision that could launch a new technical direction and lead to innovations that engender significant industrial and societal impact. Innovation, on the other hand, is a process by which ideas or concepts are translated into viable applications. The innovative process can initially be a one-person or small-group effort, but later will involve usually a large-scale, institutionally-supported, team endeavor, driven by significant and measurable operational and economical gains. In this talk, I shall relate my experiences and observations of world-class strategic research and innovation in the field of optical fiber communications at AT&T Bell Laboratories as a participant over an excited-professional-state lifetime of 40 years.Biography: Tingye Li retired from AT&T in 1998. Until then, he was a Division Manager in the Communications Infrastructure Research Laboratory of AT&T Laboratories in New Jersey. Since joining AT&T Bell Laboratories in 1957, he has worked in the areas of antennas, microwave propagation, lasers and optical communications, in which he has contributed more than 100 journal papers, patents, books and book chapters. His early work on laser resonator modes established the basis for the understanding of laser operation and is considered a classic. Since the late 1960s, he and his groups have been engaged in pioneering research on lightwave technologies and systems, which are now ubiquitously deployed in telecommunications infrastructures worldwide. His work with his colleagues on amplified wavelength-division-multiplexed transmission systems has revolutionized lightwave communications.He holds a Ph.D. degree from Northwestern University. He is a Fellow of the OSA, IEEE, AAAS, Photonic Society of Chinese-Americans, and International Engineering Consortium. He is a member of the National Academy of Engineering, the Academia Sinica (Taiwan) and a Foreign Member of the Chinese Academy of Engineering. He has received the IEEE Baker Prize, IEEE David Sarnoff Award, OSA/IEEE John Tyndall Award, OSA Frederic Ives Medal/Jarus Quinn Endowment, AT&T Science and Technology Medal, IEEE Photonics Award, and IEEE Edison Medal. He was named an honorary professor at many prestigious universities in China and Taiwan. He has been active in various professional societies, and was President of the Optical Society of America in 1995.Host: Prof. Alan Willner, willner@usc.eduLocation: Charles Lee Powell Hall (PHE) - 223

Prof. Aydogan Ozcan, UCLAAbstract:
Most of these existing cellphones are already equipped with advanced digital imaging and sensing platforms that can be utilized for various health monitoring applications. This impressive advancement is one of the central building blocks of the emerging fields of ¡°Telemedicine¡± and ¡°Wireless Health¡±. I will introduce new imaging and detection architectures that can compensate in the digital domain for the lack of complexity of optical components by use of novel theories and numerical algorithms to address the immediate needs and requirements of Telemedicine for Global Health Problems. Specifically, I will present an on-chip cytometry and microscopy platform that utilizes cost-effective and compact components to enable digital recognition and 3D microscopic imaging of cells with sub-cellular resolution over a large field of view without the need for any lenses, bulky optical components or coherent sources such as lasers. This incoherent holographic imaging and diagnostic modality has orders of magnitude improved light collection efficiency and is robust to misalignments which eliminates potential imaging artifacts or the need for realignment, making it highly suitable for field use.Bio:
Dr. Aydogan Ozcan received his Ph.D. degree at Stanford University Electrical Engineering Department in 2005. After a short post-doctoral fellowship at Stanford University, he is appointed as a Research Faculty Member at Harvard Medical School, Wellman Center for Photomedicine in 2006. Dr. Ozcan joined UCLA in the summer of 2007 as an Assistant Professor, where he is currently leading the Bio-Photonics Laboratory at the Electrical Engineering Department. In 2009, Dr. Ozcan received the NIH Director¡¯s New Innovator Award, the Office of Naval Research (ONR) Young Investigator Award, the IEEE Photonics Society (LEOS) Young Investigator Award and the MIT¡¯s TR35 Award for his seminal contributions to near-field and on-chip imaging, and telemedicine based diagnostics.
