Abstract: Metal failure in many applications, such as ballistic impact, containment, shielding, metal forming, and crashworthiness, occurs while the material is in a three-dimensional state of stress. Many previous definitions of ...

Abstract: Generalized constitutive models, which can be used in explicit finite-element analysis, are being developed to accurately model composite systems under impact conditions. These models require extensive characterization of ...

Abstract: Prior to the Columbia accident, quantitative impact assessment tools were not available to analyze debris impacts onto the Shuttle’s thermal protection system. Following the accident, the Columbia Accident Investigation ...

Abstract: The need for accurate material models to simulate the deformation, damage, and failure of polymer matrix composites under impact conditions is becoming critical as these materials are gaining increased usage in the aerospace ...
