Book Description
This report describes a study of the strength impact and fracture behaviour of a range of ceramic materials. One part of the research is concerned with ceramics which have applications as radomes or infra-red transmitting window materials, the other with ceramics with potential application in body armour. Ceramics included in the study include zinc sulphide, various glass ceramics and aluminas, silicon carbide, silicon nitride, titanium diboride and boron carbide. in one series of experiments we have measured post-impact (i.e. residual) strength curves. These experiments involve impacting specimens at chosen velocities and then measuring the residual strengths after impact. Strength is plotted as a function of velocity. Such curves give: (i) the threshold velocity above which strength degradation following impact occurs; (ii) the fall in strength above the threshold; (iii) a ready comparison with other materials or between different batches of the same material which have had, for example, different surface preparations. From these strength curves, it is ... possible to estimate the size of the flaws which control the damage. Microscopy studies of the fracture faces have been made to locate the nucleating flaws so that there is a crosscheck with the flaw sizes calculated. In cases where physical property data were not available, they were measured. Tables give data on hardness, fracture toughness, elastic moduli, stress wave and fracture velocities.

Book Description
Dynamic Failure of Materials and Structures discusses the topic of dynamic loadings and their effect on material and structural failure. Since dynamic loading problems are very difficult as compared to their static counterpart, very little information is currently available about dynamic behavior of materials and structures. Topics covered include the response of both metallic as well as polymeric composite materials to blast loading and shock loadings, impact loadings and failure of novel materials under more controlled dynamic loads. These include response of soft materials that are important in practical use but have very limited information available on their dynamic response. Dynamic fragmentation, which has re-emerged in recent years has also been included. Both experimental as well as numerical aspects of material and structural response to dynamic loads are discussed. Written by several key experts in the field, Dynamic Failure of Materials and Structures will appeal to graduate students and researchers studying dynamic loadings within mechanical and civil engineering, as well as in physics and materials science.
