Damage plasticity model for green concrete material

Abstract

Concrete damage plasticity (CDP) material model is a constitutive material model used to describe the behaviour of reinforced concrete under stress. This model is particularly useful for simulating the response of concrete structures subjected to a wide range of loading conditions. These studies aim to develop the CDP material modelling for green concrete mixture. The mixture proportion of the green concrete material was obtained from previous literature study. The material was then casted into cylindrical specimen purposely to investigate both of their elastic and plastic deformation through axial compression testing. The value of their deformation is measured by the strain gauges attached at their both sides of failure zone. The results shows that the concrete damaged plasticity (CDP) material model value in terms of their compressive crushing and tensile cracking damage. The value for compressive crushing damage was 0.0000000, 0.0000000, 0.0000000, 0.2087821, 0.4888152, 0.6959403, 0.8077879 and 0.9113505. Meanwhile, the value for tensile cracking damage was 0.00000, 0.12705, 0.25410, 0.45492, 0.56635, 0.62295, 0.68415, 0.74118, 0.79098, 0.85371 and 0.90164. By using this green concrete damage plasticity (CDP) material model, engineers and researchers can make more accurate predictions about the performance of green concrete structures, leading to safer and more cost-effective designs.
