What is being assessed?
Drawings, CAD, dimensions, supports, interfaces, known constraints and relevant simplifications.
Services
Blast, VCE & Impact Engineering
Dynamic simulation and engineering assessment for blast, vapor cloud explosion, impact and impulsive loading scenarios affecting structures and industrial systems.
Buyer problem
Pressure waves · structural response · vulnerable regions
Impulsive loads can drive local failure, support demand, connection rotation, residual deformation and damage progression in ways that static or simplified global checks cannot capture.
Method
Pressure-time histories, explicit dynamic response, CEL/ALE where justified, nonlinear materials, contact and response-history review are combined to evaluate deformation, damage and comparative mitigation options.
Deliverable
Displacement histories, stress/strain demand, plasticity/damage indicators, loading assumptions, vulnerable-zone maps, strengthening comparison and technical reporting.
Value
The analysis connects a hazard scenario to the structural regions and response mechanisms that matter for design, retrofit, inspection or further integrity assessment.
Typical inputs
What we need to scope this service.
Materials & loading
What controls the physics?
Material grade/data, preload or operating state, load history, pressure, temperature, impact/blast scenario or other relevant actions.
Decision objective
What must the analysis answer?
Local demand, failure mechanism, comparison, screening, residual response, retrofit effect, integrity concern or report requirement.
Technical depth
How Axis scopes the analysis.
01
When this service is needed
Use this service when blast, vapor cloud explosion, impact or another pressure-pulse event can control local or system response in bridges, industrial structures, tanks, supports, protective elements, connections or adjacent components.
02
Modelling depth
The analysis route may range from applied pressure-time histories to higher-fidelity fluid/structure representations for selected cases, with nonlinear constitutive behaviour and explicit dynamics where required.
03
Verification controls
Load timing and impulse, boundary-condition reasonableness, contact stability, energy behaviour, time histories, mesh sensitivity and expected response mechanisms are checked before interpretation.
04
Client value
Clients can identify vulnerable regions, compare mitigation or strengthening concepts, and translate dynamic response into practical engineering decisions.
Typical inputs
- Explosion/pressure scenario and loading definition where available
- Geometry, support conditions and relevant surrounding constraints
- Material grade and damage/plasticity assumptions
- Decision metric: deformation, damage, residual response, leakage risk or retrofit comparison
- Required reporting depth and confidentiality constraints
Scoping principle: the modelling level 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.
