Abstract: Anisotropy due to directional loading in concrete has been observed not only in the postpeak range, but also before the peak strength is reached. The traditional isotropic description of a self-similar loading surface ...

Abstract: In this study we examine the dynamic strength enhancement and the regularization properties of viscoplasticity with regard to strain softening in tension. To this end we extend the elastoplastic concrete model by Kang and ...

Abstract: The paper examines different failure modes when concrete materials are subjected to triaxial load scenarios in uniaxial and confined compression, in direct tension, as well as in shear. The different failure modes are ...

Abstract: The nonlinear behavior of concrete is complex and is governed by a variety of parameters. As a result, there exist a number of constitutive models that try to predict concrete behavior beyond the linear elastic limit. A ...
