Portfolio: FEA & CFD Verification Case Studies
Worked cases and verification studies in Code_aster, checked against closed-form solutions, published benchmarks or converged reference models, and written up as the reports clients receive.
Open-Hole Tension of Carbon/Epoxy Laminates: Lay-up and Hole Size Effects
Open-hole tension of three carbon/epoxy lay-ups in Code_aster: K_T 2.62 to 4.38, within 1.1% of theory; a 6 mm hole leaves 23 to 58% of the strength.
Mach 3 Forward-Facing Step: Wavelet-Adapted Mesh in OpenFOAM
Mach 3 step in rhoCentralFoam: a wavelet-adapted mesh matches a 4x finer uniform mesh to 0.031 in density with 21% of its cells, at 4.4x the run time.
Sandwich Beam in 4-Point Flexure: 3D FEA vs Sandwich Beam Theory
Carbon/foam sandwich beam in 3D Code_aster: 1.87 mm deflection, 3.2% from theory, 85% core shear; V and M diagrams match statics.
Potential Flow Past a Cylinder in a Channel: OpenFOAM Verification
potentialFoam flow past a cylinder: peak speed 2.01 Uā, within 0.3% of the analytical solution in a channel; the 5% gap to the unbounded case is blockage.
Steel Angle Bracket with Gussets: Shell Model Stress Check
Steel angle bracket in Code_aster with DKT shells: 0.14 mm deflection under 1 kN, 185 MPa peak von Mises, IRF 0.93 against the 200 MPa elastic limit.
Stress Concentration & Hole Edge Verification
Code_aster plate-with-hole verification: peak stress within 1.1% of Peterson's finite-width reference and compressive stress within 4.2% of Kirsch.
Loaded Pin in a Bore: Frictional Contact Verification
NAFEMS pin-in-bore frictional contact in Code_aster: contact-point displacement within 0.56% (QUAD4) and 0.43% (QUAD8) of the reference.
Tapered Panel in Shear: Element Formulation Comparison
Cook's membrane in Code_aster: linear QUAD4/HEXA8 elements under-predict deflection by 0.6% and stress by up to 1% vs QUAD8; 3D matches 2D within 0.3%.
