DOI: 10.1080/15376494.2020.1716414
Abstract: Abstract We present a recently developed three-dimensional-finite-deformation-rate form-based constitutive theory to describe the deformation and fracture of viscoelastic solids. The constitutive theory was also implemented into a commercial finite-element program. Damage and fracture in viscoelastic… read more here.
