In her book "Grunt: The Curious Science of Humans at War," Mary Roach discusses how different materials react under force during a blast. She explains that various types of materials have distinct properties, such as their ability to stretch before breaking. For instance, one material may endure up to 20% elongation without sustaining damage, while another might only tolerate a mere 5% stretch.

To address these differences, the WIAMan (Wounding in the Neuromusculoskeletal System) model is designed to be calibrated accordingly. This calibration allows for accurate predictions of the outcomes and consequences of blasts, aiding in understanding how different materials respond under extreme conditions during warfare.
