Screw Geometry: dia=5.5 mm;L=20mm; the screw material is stainless steel. but I do not have material properties. but I used these form google; yield strength =600;tensile strength=800;
Sheet geometry: plate thickness 1=2 mm ;plate thickness 2=3 mm ; length=100; width=40 mm; material properties: yield strength =250;tensile strength=320;
screw placed at 30 mm from the edges of the two plates,hole in the plates=5.5 mm Dia
I do not have pictures for the one screw test but here is picture of the 2 screws test,as shown below the screw failed by shear,
I want to find a simple method to model these screws,
I appreciate your reply
