  1. Hi all, I had modeled a steel Plates of two Cases of Same config as shown in fig. Case :1 2D PLATE 2mm Thickness, F=140N(10N/14 Nodes), constraints at opposite end. Case :2 3D hex Plate 2mm Thickness with 2 Layer of Mesh, F=140N(10N/14 Nodes), constraints at opposite end. Clarification required : 1. Both plates are same in Boundary conditions , dimensions and material property. only the element type varies but why the stress induced is different ?
  2. I have created a double sided fillet weld geometry with three plates. This was modeled using solid and shell plate techniques. The case belongs to a normal tensile loading (along X direction as per global coordinate system). Hence, it should ideally possess sigma XX in both the cases. But stress (sigma XX) in shell model is almost 0.25 times the stress obtained in solid model. The stress has been determined at a point farther away from weld, so weld modeling would not be affecting the value in the two cases. This ratio has been consistent even at different load values. I have also iterated the element size varying from 0.5 mm to 3 mm but the deviation has been consistent. So, mesh refinement might not be the reason for this. Please anyone enlighten me with the possible causes. Thanking you in anticipation. P.S : I have attached the simulation file (.fem files) for both the cases.
