Strength calculation (FEM)

What we analyse

• Plates, brackets, frames and skids (linear/static)

• Welded details and bolted joints (local stress “hot spots”)

• Shafts, hubs and interfaces (stress/deflection)

• Platforms and walkways members/strings (serviceability)

• Hoppers, chutes and lips (impact/wear zones)

• Buckling, pre-load and contact where relevant

Methods & standards

• Load cases/combinations to EN 1990/1991; steel checks to EN 1993

• Connection principles per EN 1993-1-8; weld quality to ISO 5817

• Linear static as default; in addition, non-linear contact or geometric non-linearity when needed

• Mesh convergence checks; boundary conditions reflect actual supports

• Hand calculations for sanity checks; results reported against acceptance criteria

Inputs we need
Duty (loads, cycles, temperature), interfaces and constraints, allowable deflections, as-built/site data, material specs, preferred safety factors and house standards.

Deliverables

• Calculation notes or concise report (PDF): inputs, model assumptions, results and pass/fail

• Result plots (stress/strain/deflection, factors of safety), critical sections and reactions

• Design recommendations (thicknesses, stiffeners, weld sizes, bolt classes)

• References to drawing/model items for unambiguous implementation. Therefore, vendors can fabricate with confidence.

Boundaries (so expectations match)
We do not provide civil/foundation certification, notified body sign-off or pressure-vessel code packages. However, we coordinate with your specialists and incorporate their constraints into the mechanical design.
