| 摘要： | Three-dimensional and plane stress constitutive theories and algorithms are presented for reinforced concrete plate and shell structures. Anisotropic damage mechanisms are incorporated for representing the sundry failure modes exhibited by reinforced concrete subjected to intense dynamic loadings. Viscous regularization is employed for the representation of rate-dependent effects entailed by high rates of loading, and to mitigate numerical difficulties, such as spurious mesh sensitivity, brought about by strain softening behavior. Multiple failure surface theories and algorithms are also presented so that the present work can be applied to popular models appearing in the literature (e.g., the cap model). |
