Structural FEA Analysis
Overview

What this solution covers

Our structural FEA practice delivers simulation-driven design validation — from linear static checks through advanced nonlinear, fatigue, and dynamic analysis — enabling clients to reduce physical prototyping costs and achieve first-time-right designs.
The problem

Pain points we address

Physical prototypes fail during testing, causing project delays and cost overruns

Lack of in-house FEA expertise to validate designs against customer specifications

Uncertainty about fatigue life and long-term structural reliability under service loads

Designs are over-engineered due to insufficient understanding of actual stress distributions

Our answer

What we solve

Structural adequacy assessment against applicable design codes (ASME, EN, IS)

Fatigue life prediction under constant and variable-amplitude loading

Nonlinear contact, large deformation, and material plasticity analysis

Dynamic response evaluation — modal, harmonic, random vibration, and seismic

Methodology

Our approach, step by step

1
Geometry preparation: import native CAD from SolidWorks, perform defeaturing and mid-surface extraction for shell elements
2
Mesh generation: structured hex meshing for critical regions, automatic tetrahedral meshing with convergence studies
3
Boundary conditions: apply realistic constraints and loading from test data, load spectra, or code-specified combinations
4
Solution and post-processing: run ANSYS Mechanical solver with appropriate nonlinear controls, extract von Mises stress, fatigue damage, and safety factors
5
Reporting: deliver engineering report with methodology, assumptions, results interpretation, and design recommendations
What you get

Deliverables

  • FEA methodology document with assumptions and boundary condition rationale
  • Detailed results report with stress/deformation contour plots and safety factor mapping
  • Fatigue life report with damage fractions and critical location identification
  • Design improvement recommendations with supporting parametric study data
  • ANSYS Mechanical project files for client internal review and future reanalysis
Impact

Expected outcomes

Reduction in physical prototyping iterations by 40-60% through virtual testing

Design sign-off confidence backed by code-compliant FEA evidence

Weight reduction of 15-25% through stress-driven topology and parametric optimization

Accelerated development timelines by identifying failure modes early in the design cycle

Why us

Why Shirsh

Our engineers bring deep domain expertise in structural mechanics, material behavior, and industry code compliance. We don't just run simulations — we interpret results in the context of manufacturing feasibility, code requirements, and operational reality, delivering actionable engineering recommendations rather than raw contour plots.
