I need a full finite-element workflow carried out in ANSYS Workbench (ACP + Static Structural) for a laminated composite beam subjected to three-point bending. The objective is to pinpoint where damage will first appear; in particular I want to see the onset of layer-to-layer separation rather than fibre or matrix failure. Scope • Build the laminate lay-up in ACP exactly as provided in my material schedule (I will supply ply sequence, thicknesses and orthotropic properties). • Apply the three-point bending fixture: two fixed supports at the span ends and a single central load nose. • Mesh, solve and post-process strain fields, then extract nodal or elemental strain values at the same positions as my physical strain gauges so I can compare later. • Use an appropriate delamination / cohesive or interface contact approach so the model can indicate when and where ply separation starts. • Summarise all steps, assumptions, material data, boundary conditions, convergence checks and the key plots in a concise technical report (Word or PDF). Deliverables 1. ANSYS Workbench .wbpj file with all engineering data, geometry, mesh, solution and post-processing steps intact. 2. CSV or Excel file containing the strain values at the requested gauge points. 3. Technical report describing methodology, results, damage initiation prediction and recommendations for further testing. Acceptance criteria • Maximum 5 % difference between extracted strain values and the raw ANSYS contour at those nodes. • Clear visual evidence (contours, animation or XY plots) of the first ply interface predicted to separate. • Report must be reproducible: if I reopen the project and update, results should match those presented. If you are experienced with ACP lay-ups, cohesive contacts and failure criteria in composite flexure, I look forward to seeing your approach and timeline.
