Summary Damage found on armor steel hulls in tactical wheeled vehicles following combat operations include stress cracks, deformations, fire damage, gouges and penetration. As result, the structures require repairs. Currently used repair methods are believed to degrade armor performance, which is undesirable and poses safety risk to the crew. Our study aims to determine the microstructural characteristics and mechanical properties of armor plates provided by sponsor and relate them to the materials and procedures used to fabricate and attach them to the vehicles. We plan to conduct a failure analysis of repaired upper hull plates that have shown poor performance to determine the main causes and modes responsible for their failure. The expected outcome of the project will be a technical report pointing out modes of failure, probable causes and based on findings, suggestions to prevent it.
