Numerical Simulation of the Damage Behavior of a Concrete Beam with an Anisotropic Damage Model
An anisotropic damage model was proposed to describe the nonlinear behavior of concrete beams under monotonic and cyclic loading. The hysteresis effect of concrete is approximately modeled by employing nonlinear loading/linear reloading stress paths in the model, which was implemented into ABAQUS. L...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | An anisotropic damage model was proposed to describe the nonlinear behavior of concrete beams under monotonic and cyclic loading. The hysteresis effect of concrete is approximately modeled by employing nonlinear loading/linear reloading stress paths in the model, which was implemented into ABAQUS. Linear, bilinear, exponential and Reinhardt strain softening functions are introduced to investigate their influence on accuracy of calculations.
Предложена модель анизотропного повреждения для описания нелинейного поведения бетонных балок в условиях монотонного и циклического нагружения. Поведение бетона при гистерезисе ориентировочно моделируют с использованием траектории напряжения при нелинейной нагрузке/линейной перегрузке с последующей реализацией модели в программе ABAQUS. Введены линейная, билинейная, экспоненциальная функции и функция Рейнхардта деформации разуплотнения для изучения их влияния на точность расчетов.
