Degradation of Mechanical Properties of Multi Perforated Structural Elements

Abstract

This report results from a contract tasking SOREQ Nuclear Research Center as follows: This work shall demonstrate the feasibility of an inventive method for a quantitative determination of residual strength of a punctured mechanical element due to holes perforated by many solid fragments. The research program will examine polycarbonate materials. The effort will build a material dependent damage function for all values of the area density of the holes, in particular for the dense populations whose behavior is previously unknown. The damage function will relate the average value of the residual strength of the element to the area density of the holes. Based on theoretical considerations, the damage function will be formulated as a semi-analytic function with experimentally determined material constants. Moreover, the results will be the represented in a form useable by structural strength and vulnerability computer codes.
