Abstract

The research presented here is aimed at evaluating the mechanical performance of a novel TRIP steel alloy, named TRIP-120, for different loadings cases and at various strain rates. The performance is compared with HSLA-100, a martensitic steel. The response of these materials under uniaxial loadings, as well as under biaxial stretching was investigated. The latter situation occurs together with fluid structure interaction when submitting flat circular panels to underwater impulsive loadings, using a scaled down and highly instrumented experimental apparatus. In the presented results, the TRIP-120 steel shows an improvement in performance as compared to the HSLA-100. We also investigate fracture surfaces, and the martensitic transformation of the TRIP steel. The ability of the two high strength steels presented here to sustain underwater blast loading will be compared to the one of stainless steel sandwich structures.
