  • DEMO: FEA analysis of an aircraft stiffened lug detail
    • How a “Single Corner Crack in Lug” solution compares with FEA results?
  • LEARN: Strategies for efficiently meshing 3D fracture mechanics problems
    • Mixed meshing vs. all-tetrahedral meshing along 3D crack fronts
    • Automatically-generated vs. manually-input element layers around 3D crack fronts
    • No refinements vs. geometrically graded refinements at 3D crack tip intersections
    • 100% automesh vs. “seeding" an automesh with hand-meshed nodes/elements
  • REVIEW: Sample 3D and plane strain fracture mechanics case studies
  • Summary & resources
    • SC v12.0 training options

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.

Before automeshing an assembly of close-contacting solid bodies, users may enable the "Assembly Meshing" option to enforce element face matching between neighboring surfaces (to within a user-specified tolerance). Once the solid bodies have been automeshed, StressCheck will automatically create contact zones between matched neighboring element faces and assign contact pairs via the new Auto Contact constraint method to the current constraint ID (if existing, otherwise StressCheck will use "AUTO_CONT" as the constraint ID). Individual contact pairs generated via the Auto Contact method may specified as Contact (the default, traditional multi-body contact), Fused (if element face matching was 100% successful, matched element faces are bonded) or Free (matched element faces are free). Note that if individual contact pairs are specified as Contact, and a parameter is not used for the Contact Constant, the Contact Constant value is computed from the assigned material property data and will be updated if one or more of the material properties are modified. This tutorial revisits a previous 3D multi-body contact example and utilizes assembly automeshing/automatic contact detection to significantly reduce the amount of setup time for multi-body contact analysis. The tutorial also demonstrates how refining the automesh (or updating a parameter value which triggers a re-mesh) will result in the re-generation of the contact zones/contact pairs.]]>

]]> StressCheck Tutorial: New Mesh Seeding Features in StressCheck v12.0 https://www.esrd.com/resource-library/product/stresscheck-tutorial-new-mesh-seeding-features-in-stresscheck-v12-0/ Wed, 11 Sep 2024 19:41:16 +0000 https://www.esrd.com/?post_type=product&p=32641 A new and powerful mesh seeding feature is now available with the release of StressCheck v12.0. Before automeshing a solid body, users may associate manually generated nodes and/or manually meshed elements with that solid body. During the automeshing process, these nodes and/or elements will be incorporated in the resulting mesh. If users require refinement of the seeded mesh, h-Discretization methods are supported. Note that the automesh must be re-generated after h-Discretizing the seeded mesh. This tutorial revisits the example from the Getting Started Guide and utilizes seeded hand-meshed elements in the region of interest. The hand-meshed elements are then h-Discretized and the automesh is updated.]]>
