An Experimental Study on Strain Hardening of Amorphous Thermosets: Effect of Temperature, Strain Rate, and Network Density

Abstract: 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 performed at two different strain rates spanning the glass transition region. The results show that a more pronounced hardening response can be observed as decreasing temperature and increasing strain rate and network density. We also use the Neo-Hookean model and Arru… Show more

“…In recent decades, VOFC has been used to model nonlinear viscoelastic behaviors associated with a time-dependent evolution of various materials [19][20][21][22][23] due to its advantages of depicting the memory property over time or spatial location. 24,25 However, the development of VOFC is not as satisfactory as that of COF, which may be mainly attributed to the following three reasons.…”
