An internal variable theory for isotropic visco-elastic-plastic solids : application to indentation of amorphous polymeric solids
(Massachusetts Institute of Technology, 2003)
A significant advance in modeling the plastic deformation of amorphous polymers has been made by Parks, Argon, Boyce, Arruda, and their co-workers (e.g. Parks, Argon, & Bagepalli, 1985; Boyce, Parks, & Argon, 1998; Arruda ...
Design and use of a fixed-end low-load material testing machine
(Massachusetts Institute of Technology, 2000)
The purpose of this low-load material testing machine is to provide students an opportunity to perform basic material tests on their own instead of watching a lab technician, thus improving the student's lab experience. ...
A thermo-mechanical finite deformation theory of plasticity for amorphous polymers : application to micro-hot-embossing of poly(methyl methacrylate)
(Massachusetts Institute of Technology, 2007)
Amorphous thermoplastic polymers are important engineering materials; however, their nonlinear, strongly temperature- and rate-dependent elastic-visco-plastic behavior has, until now, not been very well understood. The ...
