High-Fidelity Physics-Based Modeling of CLT

TR-19-35.1

This report summarizes a series of high-fidelity physics-based (HFPB) calculations pertaining to the blast response of cross-laminated timber (CLT) panels. The primary objective of this HFPB modeling effort was to assess the ability of a continuum finite element approach to model CLT panels under complex quasi-static and dynamic (i.e., those associated with explosions) loading conditions. Panel responses both prior to and following rupture were considered. The modeling approach aimed to include the necessary fidelity to capture complex stress states explicitly while remaining feasible from a computational cost perspective.
