Structural composite panel performance under long-term load

Abstract

Information on the performance of wood-based structural composite panels under long-term load is currently needed to permit their use in engineered assemblies and systems. A broad assessment of the time-dependent properties of panels is critical for creating databases and models of the creep-rupture phenomenon that lead to reliability-based design procedures. This paper presents a broad background of information on the creep-rupture phenomenon by describing the microscopic mechanisms of creep-rupture, presenting models commonly used to describe creep deformation and time-to-failure behavior, and reviewing literature on structural particle boards, flakeboards, and plywood. A large test program and future research needs in the field are also described.
