Shock and Damage in Marine Composite Structures.
Abstract
This report is a summary of our recent efforts here at NRL in developing a methodology for predicting the response of thick composite materials subjected to multidimensional shock loadings. A focus of this work has been the development of a 1D, 2D, and 3D evolving damage theory applicable to highly transient loading environments such as underwater shock and impact. This approach is phenomenological in nature and has achieved a degree of success. Comparisons to 2D composite plates impact experiments have been very encouraging. in this work, we assume a local material damage and effective resiting area perspective, in which the evolving damage is considered to be a vector quantity. The iD theory includes explicit dispersion/viscoelastic effects as well.
