Hello, I am doing micro modeling of brick masonry in Abaqus. I need to define complete stress-strain curve for brick and mortar, but from experimental data i have only COMPRESSIVE STRENGTH and ELASTIC MODULUS. So, how to get these complete stress-strain curves? Is there any code or research work, from which we can develop complete stress-strain curve? I have found some relations but they are for concrete, can we use those? thank you
