WebApr 11, 2024 · If the stress‒strain curve has a downwards trend, the ultimate stress is the stress corresponding to the local peak point, such as in the curves of SCFSTs with in-built CFRP tubes. Otherwise, the peak stress corresponds to the maximum stress within the range of 5–10 mm of the total deformation, Calculating models Webstrain rate if properly designed, due to the mechanism of SHPB, it is difficult to obtain the complete stress–strain relationship incorporating the long stress plateau [26]. In the intermediate strain rate range, complete stress–strain curves can be obtained with drop-weight test, but the loading strain rate is not rigorously constant. inter-agency insurance service knoxville tn https://tommyvadell.com
