SHD Sim Explicit
Impact and crash
Vehicle and structural crash
OpenRadioss
In development.
This module is phase 5 — a market decision more than a technical one. The solver behind it is chosen and its capability is known. SHD Sim is available today.
What it is
Explicit time integration with a time step set by how fast a stress wave crosses the smallest element: microseconds, millions of steps, and no equilibrium iteration at all. That is what makes it right for events where the structure is far past yield and contact changes every step, and wrong for anything slow.
What this analysis needs from you
- Strain-rate-dependent material data, which is a test programme in itself
- Contact defined across everything that might touch
- Substantial compute, and an energy balance check to know the answer is physical
Typical uses
- Vehicle crash and occupant protection
- Structural impact and barrier testing
- Rollover and roof crush
- Component-level crush assessment
Industries
Sectors where this analysis is routinely asked for.
- Automotive safety
- Rail crashworthiness
- Aerospace
- Packaging
What comes out
- Crush behaviour and folds
- Deceleration pulses
- Energy absorption history
- Intrusion measurements
Backend
OpenRadioss
Chosen for this analysis type, with its capability verified against the module plan — not decided later.
Status
Phase 5 — a market decision more than a technical one. Telling us you need this analysis moves it up the order — modules are sequenced by who is waiting for them.
