Sustainability, 2022 The strength of concrete elements under shear is a complex phenomenon, which is induced by several effective variables and governing mechanisms. Thus, each parameter’s importance depends on the values of the effective parameters and the governing mechanism. In addition, the new concrete types, including lightweight concrete and fibered concrete, add to

A Plastic-Damage Model for Lightweight Concrete and Normal Weight Concrete [PDF]
International Journal of Concrete Structures and Materials, 2008 A new plastic-damage constitutive model applicable to lightweight concrete (LWC) and normal weight concrete (NWC) is proposed in this paper based on both continuum damage mechanics and plasticity theories. Two damage variables are used to rep- resent tensile and compressive damage independently.
