Abstract
Toexplorethedeformationmodesofwarshipstructuressubjectedtoclose-rangeexplosionofwarheadandfurnishexperimentaldata,thedeformationanddamagemodesofclampedlargescalesquareplatesunderclose-rangeblastloadingwereanalyzedthroughmodelexperiments.Onthebasisoftheanalysis,thefailurestrainofQ235steelwasobtainedutilizingbiaxialstrainhypothesisandbulkequivalenttheoryviameasuringthethinningrateofcrackedpetals.Basedontheexperimentalresults,arupturecriterionofstructuressubjectedtolocalisedblastloadingwaspresentedafteremployingrigid-plasticassumptionandenergydensityrule.Moreover,predictionsforexperimentsweremade.Theresultsshowthattheclampedplatesexhibitthreedifferentdeformationanddamagemodeswiththeincreasingoftheloadintensity.Thepredictionsbymakinguseoftherupturecriterionfortestconditionscorrelatewellwiththeexperimentalresults.
