Dynamic Rate Dependent Elastoplastic Damage Modeling of Concrete Subject to BlastLoading: Formulation and Computational Aspects

摘要

Advanced elastic-damage and elastoplastic-damage models are presented within theframeworks of both continuum damage mechanics and micromechanical damage mechanics. Novel energy-based coupled elastoplastic continuum damage theories and computational algorithms are proposed, including rate-dependent isotropic and anisotropic damage models. Efficient constitutive algorithms and extensive experimental validations are also performed. In addition, novel finite deformation elastoplastic continuum damage models are developed to account for large strains and high rates. On the other hand, advanced and state-of-the-art
