This paper reviews the efforts of the author and his colleagues over the past five decades to develop mesomechanical models of material failure. In the early 1970s a procedure known as the NAG/FRAG (Nucleation and Growth to Fragmentation) methodology was introduced by a group at SRI International. Experiments are performed in which the evolution of micro structural damage is measured posttest as a function of stress, time‐at‐stress, temperature, and other environmental parameters. Damage nucleation and growth functions are deduced via iterative computational simulations. I conclude the review with a discussion of a current challenging problem: that of designing improved glass and ceramic armors.
