NettetHow to calculate the absorbed energy by the stress strain curve? In some papers, the authors calculated the absorbed energy of the materials by the true stress strain … Nettet13.1.2.4.1 Stress–strain curves. The stress–strain curves look different for compression and extension loadings. The main reason is that the nominal stress is used where it is defined by the load divided by the specimen area where the area changes. The nominal strain is defined by the length change divided by the original length.
