| Abstract Scope |
Gradient theories of elasticity, plasticity and damage have become increasingly popular during the last decades due to their ability to eliminate undesired singularities, calculate widths and spacing of shear bands and interpret size effects. Another major feature is the elimination of mesh-size dependence of finite element calculations in the material softening regime. Typical original contributions and reviews are listed in [1-7] and references quoted therein. In this presentation we first show that the author’s ILG framework is sufficient for modeling all major experimentally observed phenomena that non-gradient theories cannot address. Then we extend the ILG framework to include internal times and stochastic effects. Finally, a discussion of incorporating fractionality/fractality and multiphysics effects (chemical, electrical) is given. |
