<p>Hello!<\/p><p>I am trying to perform a simulation where a metal blade (rigid body) penetrates a hyperelastic tissue (Ogden model). To represent the damage of the tissue while preserving the initial mass, I modeled the part that comes into contact with the blade using the SPG section (KERNEL = 1; ITB = 3; ISC = 1). I have tried to include material failure both through the SPG section using the IDAM variable, and through the *MAT_ADD_EROSION keyword.<\/p><p>However, the simulation results do not seem sensitive to the values I input for material failure: the blade penetrates deforming and cutting the SPG part even when I disable material failure.<\/p><p>What could be the explanation for this behavior?<\/p><p>Thank you very much in advance.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-387683","topic","type-topic","status-publish","hentry","topic-tag-FailureModel-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
