Estimation of residual stresses by inverse analysis based on experimental data from sample removal for “small punch” tests

• Both stresses and material properties can be identified by Small Punch tests modified according to the present proposal. • Displacements due to stress relaxation are measured by Digital Image Correlation instruments. • Test simulations and back-analyses are procedures here elaborated and computati...
