Dynamic System Response of Truss Panels under High Dynamic Loading through Experimental & Computation Evaluation

摘要

The ability of computer simulations to accurately resolve dynamic responses of systems has significantly improved over the last decade. Simulations can now be a trusted source of parametric evaluation of complex systems. DARPA funded a program to investigate the dynamic performance of truss panel systems. Two configurations were computer simulated and their material responses were characterized. This manuscript documents the validity of computer simulation to correlate experimental system failure limits under dynamic load. The computer code matched the experimental outcome in system failure response and residual velocity under high impact. The code can be used in the future to analyze more complex geometries.
