Stress Analysis
Performance-driven, validated solutions for complex mechanical systems through advanced analysis, modeling, and design expertise
Stress analysis is a foundational tool in mechanical and structural engineering, used to evaluate whether components can safely withstand applied loads without failure. At ENA2, we apply advanced Finite Element Analysis (FEA) techniques to assess stress, strain, and deformation under a wide range of static and dynamic conditions — helping our clients design safer, more reliable products.
Linear and Nonlinear Stress Analysis
Linear Stress Analysis is suitable for elastic materials and small deformations where stress and strain follow a proportional relationship. This is often used for early-stage design validation and factor of safety (FoS) calculations.
Nonlinear Stress Analysis accounts for large deformations, plastic behavior, and complex interactions. It is essential for accurate evaluation of real-world behavior in components experiencing yielding, large strain, or contact interactions.
Stress Analysis for Structural Integrity
We specialize in modeling challenging real-world scenarios that require:
Contact Analysis:
Includes surface interactions such as friction, sliding, separation, and interference fit conditions.
Material Nonlinearity:
Simulation of hyper elastic materials (e.g., Mooney-Rivlin, Ogden models) for rubber, seals, and polymer components.
Geometric Nonlinearity:
Captures large displacements, buckling, or collapse behavior under high loads.
Multistage Analysis:
Sequentially applies loads and boundary conditions to replicate actual assembly or operational steps (e.g., bolt preloading, press fits, thermal-mechanical cycling).
Evaluation Metrics
Our stress analysis workflow provides critical insights into:
- Stress concentrations and failure-prone regions
- Load paths and deformation modes
- Structural margins and Factor of Safety under worst-case loading
These insights help clients optimize material usage, validate product designs, and ensure compliance with applicable codes and standards.
