Senior-level finite element analysis for complex structural problems — nonlinear materials, contact mechanics, fatigue life prediction, and vibration. Automotive and aerospace experience. Results your team can defend.
Your internal team handles standard linear load cases fine. But when the physics get nonlinear — large deformations on PPGF30 housings, creep in PA66GF30 under thermal cycling, rubber seal compression sets, fatigue at weld lines nobody predicted — you need a specialist who's worked through these failure modes hundreds of times.
The large consultancy model makes this worse, not better. A senior engineer sells the engagement. A junior analyst runs the model using isotropic datasheet properties on a glass-fiber part. You get a colorful stress plot that looks convincing until the part fails at the weld line — exactly where the fiber orientation drops to 15% of the bulk value and the datasheet properties are meaningless.
Each capability below represents analysis work we run routinely, not occasionally. The descriptions are written for engineers, not marketing departments — they tell you when the analysis is appropriate and what failure mode it's designed to catch.
Linear analysis for stiffness checks and load-path studies. Nonlinear analysis when contact, large deformation, or material nonlinearity changes the result meaningfully — which is more often than most teams assume.
Natural frequency extraction to identify resonances. PSD-based spectral analysis to compute 1σ RMS stress response under road-load excitation — the analysis automotive brackets need but rarely get before DVP failures.
High-cycle (S-N) and low-cycle (ε-N, Coffin-Manson) fatigue life. IIW weld fatigue assessment. Goodman and Morrow mean-stress correction for non-zero-mean load histories. Multiaxial fatigue for stress states not dominated by a single principal.
Time-dependent creep for PA66GF30 and PA66 components under sustained thermal-mechanical loads. Norton power-law and time-hardening models calibrated to temperature-dependent test data. Predicts dimensional instability and stress relaxation in fastened joints.
Mooney-Rivlin, Ogden, and Arruda-Boyce material models for elastomers. Compression set, sealing lip contact pressure maps, and O-ring extrusion analysis. Material coefficients fitted from compression or biaxial test data when available.
Bolt pretension modeling with realistic clamping force distribution. Joint separation under combined thermal and mechanical loads. Linear and nonlinear buckling for slender structures. Thread engagement analysis and torque-to-clamp-force correlation.
Each material system below represents years of daily analysis work — not occasional projects. The modeling decisions that matter for each are different, and generic FEA approaches get them wrong.
The defining challenge: fiber orientation controls mechanical properties, and fiber orientation is controlled by the injection molding process. Isotropic datasheet properties are wrong at weld lines by 200–300%.
We use process-aware material models informed by Moldflow fiber orientation tensor mapping, combined with multilinear isotropic hardening (MISO) to capture the nonlinear stress-strain behavior beyond the elastic limit.
Rubber behaves nothing like a linear elastic material. Large strains (100–500%), incompressibility (ν ≈ 0.499), and strong rate-dependence require hyperelastic formulations — and the choice of model matters more than most analysts realize.
Mooney-Rivlin is appropriate up to ~100% strain. Ogden handles larger deformations and better captures the upturn at high strain. Arruda-Boyce is preferred when calibration data is limited — it extrapolates more physically than polynomial models.
For metals, the analysis challenge shifts from material modeling to load history characterization and local stress assessment. Sheet-metal brackets with spot welds require IIW fatigue class assessment. Superalloys at high temperature require temperature-dependent plasticity and creep.
For aerospace hot-section components (CMSX-4, IN718), we use anisotropic elasticity for single-crystal materials, temperature-dependent cyclic plasticity, and Coffin-Manson LCF life prediction with scatter-factor corrections per certification requirements.
