Abstract

Aslideline/erodingalgorithm,whichwasimplementedintothe2DLagrangianelasticityplasticityhydrodynamiccodeLTZ- 2D,wasimproved.Thecellerodingcriterionwaschangedfromthe accumulativeplasticstraintoanintegratedcriterionmadeoftheaccumulativeplasticstrain,thedimensionlessstiffnessfactorandtheangleoppositetheslideline. Andthepenetrationproblemswere numericallysimulatedbytheimprovedalgorithm.Calculatedresultsdisplaythattheimprovedalgorithmcanresolvetheinterfacebetweenthetwoimpactingbodiesandsmoothoutthecurvatureofth slideline.
