Finite Element Analysis (FEA)

Our Finite Element Analysis (FEA) services assess Stress, Strain, Fatigue, Deflection, for plant and equipment in mines, farms, and municipal works. rang Imagineering offers specialist Finite Element Analysis (FEA) services to assess stress, strain, fatigue, and deflection in plant equipment, mobile plant, and operational infrastructure.

FEA is also used to verify the structural performance of welded frames, support brackets, equipment skids, and other components subject to mechanical loading.

Our engineers use advanced simulation software to help clients identify risks, optimise designs, and meet compliance standards.

Service Inclusions:

  • Structural stress and deflection analysis

  • Fatigue life assessment and crack growth prediction

  • Modal and Vibration analysis

  • Pressure vessel and tank integrity modelling

  • Lifting equipment and load handling assessment

  • Dynamic and thermal analysis for operational plant

Why Choose Trang for FEA?

We specialise in practical, operationally focused analysis — not just theoretical models. Our FEA outputs are designed to be understandable by site personnel and integrate into maintenance and upgrade strategies.

We regularly perform simulation work on components that form part of broader structural assemblies, including platforms, tanks, access frames, and structural supports.

Typical Mechanical Engineering Consulting Assessments:

Platforms, Stairs, and Handrails

These items are extremely common on worksites and they need to be compliant for strength as well as various usability standards. Additional requirements must often be considered too, depending on the various plant and equipment items that your platforms, stairs or handrails interact with.

Man Baskets

Man baskets are critical for the safety of your team.
They need to be structurally sound, and they must comply with different requirements depending on their application.

Lifting and Spreader Beams

Lifting beams are often subject to complex loading scenarios. These items must be checked to ensure they are structurally suitable to protect not only the object being lifted but also any surrounding personnel.

General Strength Analysis

Many items are subject to loading, including lifting eyes, tow points and bearing arrangements. Trang can simulate these loading scenarios using various analysis tools to make sure they are structurally sound and compliant with all relevant safety codes.
