ABAQUS MODELS AND MATERIAL

Determining the range of Young's modulus and stress – strain curve ased on the stress-strain diagram, the first section of the curve is a straight or almost straight line for which the expression of Young's modulus is used. Young's modulus of concrete which increases with increasing compressive strength is affected significantly by the Young's modulus of aggregate and its volumetric ratio in the concrete. Some B
