hi

i wana to investigate effect of crack in lamb wave propagation in composite plate in abaqus software. to this end, i have modeled a composite plate using 3Dshell defomable planar part. Also, i modeled crack using seam tool. i have problem in defining contact between two edges of crack to transmit wave through it. can anybody help me please?
