WebJul 18, 2024 · We can notice the strain softening behaviour of concrete once the curve reaches its peak at 𝜀𝑐1. 𝜀𝑐1 is the compressive strain at maximum stress. 𝜀𝑐1 gets bigger as the concrete grade increases. In other words, higher grade concrete will be able to undergo larger strain before it starts to soften. Strain softening happens to ...
