The Auto Contact method allows the user to manually toggle between "Contact" (default), "Bonded" or "Free" options, enriching the range of possibilities when performing hierarchic modeling of 3D fastened assemblies.
  • In the first simulation, traditional multi-body contact (i.e. the "Contact" option) is automatically generated for all matched surfaces during Assembly Meshing, and each plate/fastener body is solved independently for pressures/stresses.
  • In the second simulation, the existing Auto Contact constraints on the top/bottom surfaces of the middle plate are set to the "Free" option and the existing Auto Contact constraints between the middle plate and associated fastener shank surfaces are set to the "Fused" option.
    • This means the middle plate/fasteners are solved as one continuous body, thereby reducing the model hierarchy from six (6) independent bodies to three (3) independent bodies.
  • Upper and lower plate bore stresses for each multi-body contact simulation are then compared.

]]> StressCheck Tutorial: Comparing Pre- and Post-Repair Configurations via Fused Auto Contact https://www.esrd.com/resource-library/product/stresscheck-tutorial-comparing-pre-and-post-repair-configurations-via-fused-auto-contact/ Wed, 04 Dec 2024 22:04:11 +0000 https://www.esrd.com/?post_type=product&p=32919 In this StressCheck v12.0 tutorial, solutions of pre-repaired and post-repaired model configurations will be performed using Assembly Meshing/Auto Contact in combination with Parts & Solution Configurations.
  • In the pre-repaired configuration, a 3D panel with a circular cutout under axial loading will be analyzed for detailed stresses.
  • In the post-repaired configuration, a circular tapered doubler patch will be bonded over the circular cutout (via the "Fused" Auto Contact option now available in StressCheck v12.0) and analyzed for detail stresses.
  • Direct and meaningful comparisons will be made between the pre-repaired and post-repaired configuration stress distributions.
