Discrete Element Study on the Mechanical Response of Soft Rock Considering Water-Induced Softening Effect

Applied Sciences
Soft rocks are prone to softening upon contact with water, and their rapid deterioration in mechanical properties is a significant cause of instability and failure soft rock masses. Besides, the macroscopic mechanical response of rocks is closely related

On a damage-plasticity approach to model concrete failure

, 2009
A damage-plasticity constitutive model for the description of fracture in plain concrete is presented. Two approaches, the local model comprising the adjustment of the softening modulus and the nonlocal model based on spatial averaging of history ...
