Plastic deformation of glassy polymethylene : computer- aided molecular-dynamic simulation

Molecular dynamic simulation of low temperature plastic deformation (Tdef = 50 K, Tdef/Tg ≤ 0.3) is studied for glassy polymethylene under the regime of active uniaxial compression and tension for a cell composed of 64 chains containing 100 –CH2 groups in each (as united atoms) and with periodic boundary conditions. Thirty two such cells are created, and, in each cell, polymethylene chains in t...

Computer Aided Molecular Modeling Of Membrane Metalloprotease

Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

CAPS: Computer-Aided Plastic Surgery

This thesis examines interactive computer graphics and biomechanical engineering analysis as components in a computer simulation system for planning plastic surgeries. A new synthesis of plastic surgery planning techniques is proposed based on a task-level analysis of the problem. The medical goals, procedures, and current planning techniques for plastic surgery are reviewed, and from this a li...

Molecular Dynamics Simulation on Plastic Deformation of Metallic Nanowires

We have studied the initial stage of plastic deformation behavior of metallic nanowire of pure nickel, by using molecular dynamics methods. In these simulations, we applied uniform strain along c-axis at strain rate of 0.5%/100ps, 0.5%/10ps and 0.1%/2ps. We have observed the formation of stacking faults by movement of a partial dislocation, and the development of stacking faults to deformation ...
