摘要：

The viscoelastic/rate-sensitive plastic constitutive law to describe the non-linear, anisotropic/asymmetric and time/rate-dependent mechanical behavior of fiber-reinforced (sheet) composites were developed as discussed in Part I along with experimental procedures to obtain the material parameters for the woven fabric composite. Here, numerical formulations were developed. For verification purposes, finite element simulation results based on the proposed constitutive law were compared with experiments for the time-dependent springback in rate-dependent three point bending tests.
