This document describes numerical modeling work conducted by Pierluigi Olmati from 2010-2013 while a PhD student at Sapienza University of Rome. It focuses on modeling the response of precast concrete sandwich wall panels to close-in detonations of explosive charges. The document outlines Olmati's educational background and timeline, provides details on the numerical models created to simulate the detonation scenario and different panel configurations, and presents results validating the model against previous experimental blast tests.
