About this workflow view
All blocks keep the CREATE / DISCOVER / SIMULATE positions, with Equipment below Geometry; unused records remain disconnected. This changes the view only, not the exercise records. The diagram shows the setup, not solved results.
∑ Used models & submodels
Only models assigned to records used by this exercise are listed here. The full-layout option preserves the supplied starter records; no Workbench records are changed.
Euler–Bernoulli beam · Linear static · ASTM D7264 · Three-point flexure · Procedure A load
Beam bending uses effective laminate axial stiffness, the linked section geometry, support span and applied loading. Euler–Bernoulli deflection excludes transverse shear deformation, roller contact and indentation. Ply stress recovery for rectangular laminate coupons is separate from section-level beam stress recovery.
∑ Theory & assumptionsData travelling between blocks
Materials → Laminates
Stored ply stiffness, strength, density and expansion properties.
Virtual Test → Simulation
SIMULATION selects this case and its analysis model; the case owns its applicable cycle and input references.
Laminates → Virtual Test
Ply angles and thicknesses, stiffness, mass and ply properties.
Geometry → Virtual Test
Part shape and dimensions, thickness or section definition, and model-specific geometric inputs. Each selected case consumes only the dimensions its model supports.
Equipment → Virtual Test
Linked testing machine and fixture: load capacities, fixture type, specimen-fit and support-span limits, and mounted setup dimensions. The selected test case supplies the applied loading; hardware limits are checked against its setup.
Models → Virtual Test
Applied model assignment: Euler–Bernoulli beam · Linear static. Model parameters and formulation are used by Virtual Test.
Inspect specimen width, laminate thickness, support span and central force.
Models: Euler–Bernoulli beam · ASTM D7264-26-based
