A three dimensional constitutive model for plain cement ...

2019-4-10  1. Introduction. Cement concrete is a widely used material in construction. Development of a robust constitutive relation for concrete is essential for safe and economical construction of buildings and infrastructures. Consequently, from the early 19th century, researchers have proposed a stress-strain relationship to model the plain concrete.
