Advanced Numerical FEA & ASME Section VIII Div 2 Design-by-Analysis
When standard empirical design-by-rule equations reach their geometric or pressure limits, Finite Element Analysis (FEA) provides the essential mathematical proof of structural safety. COREX Engineering provides advanced linear and nonlinear FEA simulation services for complex pressure vessels, heavy piping components, high-load structural joints, and specialized industrial equipment.
Our simulation engineers possess deep expertise in ASME Section VIII Division 2 Part 5 Design-by-Analysis (DBA), performing elastic stress categorization, limit-load plastic collapse evaluations, local failure strain checks, and cyclic thermal fatigue life predictions.
Key Technical Deliverables
ASME Section VIII Div 2 Part 5 (DBA)
Complete Design-by-Analysis reports covering protection against plastic collapse, local failure, buckling, and cyclic fatigue.
Linear & Nonlinear Stress Categorization
Stress linearization across critical paths (SCL) to decompose total stress into membrane, bending, and peak components.
Complex Vessel Nozzle Junction Stresses
Detailed solid meshing around non-standard hill-side nozzles, large d/D ratios, and reinforced pad configurations under heavy piping loads.
Thermal Transient & Heat Transfer FEA
Transient temperature distribution modeling during plant startup/shutdown cycles to predict thermal stresses and avoid thermal shock.
Fatigue Life & Fracture Mechanics Audits
S-N curve fatigue screening and cumulative damage factor calculations under repeated thermal and pressure cycle loading.
Modal & Harmonic Vibration Analysis
