A series of uniaxial compression tests are performed on amorphous thermoplastics poly (ethylene terephthalate)-glycol (PETG). The stress response shows a dramatic change with temperature and strain rate, including the modulus, yield strength and stra

Amorphous glassy polymers are widely used as structural materials. However, their mechanical properties continuously evolve with physical aging, which significantly influences their applications. In this work, we investigate the effects of aging on s

Understanding the structural relaxation plays an essential role in the application of amorphous solids. Most of the current models use the fictive temperature concept to describe structural relaxation. The fictive temperature is assumed to evolve wit

The low recovery stress has limited utilizing shape-memory polymers (SMPs) as actuators. In this work, we demonstrate that the resultant recovery stress of amorphous SMPs can be significantly increased through cold programming. A three-dimensional mo

In this paper, we present an experimental study on strain hardening of amorphous thermosets. A series of amorphous polymers is synthesized with similar glass transition regions and different network densities. Uniaxial compression tests are then perf
