NONLINEAR FEA SIMULATION OF THORAX DYNAMIC RESPONSE UNDER BLAST LOAD

摘要

Blast overpressure can cause severe injuries of several organs ranging from local injury to collapse or rapture of vital organs rapidly and death. This paper will investigate the thorax dynamic response for blast loading. The presented numerical blast tests will accompany the introduction of new material modeling details. Reliable and robust analysis explicit finite element analysis software (ANSYS and LS-DYNA) will be used to complete 3D finite element model and conduct numerical testing.
