Services
Industrial Structural-Integrity Simulation
Local finite element assessment for industrial assets where connection behavior, supports, discontinuities, thermal gradients, or accidental loads control integrity decisions.
Buyer problem
Vessels · piping · flanges · saddles · supports
Industrial systems often fail at details: flange faces, bolted joints, nozzles, saddles, pipe transitions, support brackets, and stiffness discontinuities. A shell-only or isolated component model may miss the actual pathway to loss of containment.
Method
Axis models relevant assemblies with local refinement, contact, boundary-condition review, structural load transfer, plastic strain screening, reaction-force histories, and critical-zone interpretation. The level of modelling is matched to the engineering question and available data.
Deliverable
Outputs can include critical-region maps, PEEQ or stress/strain screening, support reaction histories, connection-level interpretation, mitigation priorities, and a concise decision-support report.
Value
The work helps prioritize inspection, reinforcement, local shielding, support redesign, isolation planning, or additional code/fitness-for-service checks.
Typical inputs
What we need to scope this service.
Materials & loading
Material grade, available test data, load history, temperature, pressure, blast/VCE or operating assumptions.
Decision objective
What the simulation must answer: local stress, damage indicator, comparison, screening, report or research evidence.
Technical depth
How Axis scopes vessels, piping, flanges, supports and connection-critical industrial systems.
01
When this service is needed
Use this path when the integrity question is local rather than global: flange rotation, gasket unloading, nozzle distortion, saddle support reaction, pipe–vessel transition stress, equipment-support demand or local plastic deformation under accidental or operating loads.
02
Modelling depth
Axis can model shell–solid assemblies, tied or contact interfaces, saddle supports, piping branches, flange regions, gravity, internal pressure, thermal or dynamic loading and screening metrics such as stress, strain, PEEQ, displacement, reaction force and history output.
03
Verification controls
The review focuses on load paths, support reactions, contact choices, mesh quality at discontinuities, shell-to-solid compatibility, stress/strain localization and whether the chosen screening metric is appropriate for the stated decision.
04
Client value
The result helps clients decide where reinforcement, inspection, blast shielding, layout change, leakage review or more detailed assessment should be prioritized before spending effort on the wrong part of the system.
Typical inputs
- Vessel, pipe, flange, support or equipment geometry
- Operating and accidental load scenarios
- Material grades, thicknesses and connection assumptions
- Known inspection findings or suspected vulnerable zones
- Desired screening metric and reporting format
Scoping note
The level of modelling is selected after reviewing the engineering question, available data, uncertainty and required decision. Axis does not recommend high-complexity simulation when a simpler verified check is more appropriate.
