Abstract:

A methodology suitable for predicting the damage inflicted upon armor panels by blast from nearby high explosive detonations has been developed by extensive modifications of an existing finite-difference structural response code. A new constitutive formulation involving prescribed through-thickness stresses was introduced to account for the effects of intense surface pressures. A triaxial stress criterion for material failure has been incorporated into the analysis to permit prediction of panel rupture and of post-failure response. This methodology was then applied to a case for which comparable experimental results are available. Author
