LS-DYNA Blast Response Analysis

I have the full geometry and material cards for an NRC reinforced-concrete slab and now need an LS-DYNA simulation that captures its dynamic response to an air-blast load. The priority output is precise displacement-time histories and corresponding deformed-shape plots; any additional insight you can extract is welcome.

The task involves importing the supplied model, applying the pressure-time curve that represents the blast, defining realistic boundary conditions to mirror our lab set-up, and running an explicit analysis. Please document every modelling choice—element formulation, contact, damping, control cards—so the study can be reproduced without ambiguity.

Deliverables
• LS-DYNA keyword file (.k) ready for execution
• Result databases (d3plot, binout, etc.)
• CSV/graphs of nodal displacements over time
• Concise technical note outlining assumptions and key findings

Geometry and material data will be provided immediately after agreement is in place, so you can start right away. Proven experience with blast or high-rate concrete simulations in LS-DYNA—ideally using MAT_072R3, MAT_159, or similar—is essential. Familiarity with LS-PrePost, MATLAB, or equivalent tools for post-processing will help present the displacement data clearly.

Please outline your expected turnaround and the compute resources you plan to use when you reply.
