Computational Mechanics Laboratory(CML) has been formed in early Fall
of 1997 within the Department of Mechanical Engineering, IUPUI. This research
laboratory is an integration of the facilities and expertise of the previous
CAD/CAM and Computational Biomechanics Laboritories of the department.
The primary mission of CML is to conduct interdisciplinary research in
the development and applications of the finite element method for the solution
of problems in solid mechanics. The present applications are in the following
main areas: Electronic Packaging Advanced Materials System Simulations
Biomechanics
Electronic Packaging The research in this field is directed towards developing fatigue life prediction methods for solder joints of electronic packages. Viscoplastic creep models are coupled with energy-based creep models for prediction of fatigue life of solder joints. Experimental correlations are obtained for validation of the developed fatigue life predictions. Other activities in this field include: 1) fatigue crack propagation in solder joints under thermal loads, 2) viscoelastic creep models for conductive adhesives lead-free interconnect materials. Experimental and numerical studies are conducted for understanding the behavior of epoxy adhesives under thermal loads. Advanced Materials The research in this area includes three-dimensional fracture prediction of cord-rubber composites, aeroelastic analysis of composite plates/shells, hierarchical/micromechanical analysis to predict constituent properties in composites, vibration analysis of reinforced rubber structures, and strain distribution models of dental bridge superstructures made from different materials. The developed finite element models are compared with experiments. System Simulations The research in this field involves developing system simulation models for performance evaluation and design of drive trains in automotive applications. Biomechanics The research in this area involves development of computational models for understanding the behavior of biological systems. Models for fatigue life studies of human bone, mechanical behavior of human temporomandibular joint, dental appliance evaluations, dental implant behavior, and stiffness characteristics of smooth muscle tissue using viscoelastic and composite models constitute the recent research activities in this area. The studies on the biomechanics of bone include three-dimensional modeling of bone microstructure, bone adaptation using an isotropic strain criterion, fatigue simulation of dog bone under four-point bending loads, damage accumulation of bone under different loading conditions, and anisotropic damage investigation to determine how the bone withstands microdamages in different directions. |
