RISSimulations of Non-Gaussian Property Fields Based on the Apparent Properties of Statistical Volume Elements
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The properties of composite materials with random microstructures are often defined by homogenizing the properties of a representative volume element (RVE). This results in the effective properties of an equivalent homogeneous ...
Automating the Derivation of the Equations of Motion of a Multibody Dynamic System With Uncertainty Using Polynomial Chaos Theory and Variational Work
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Understanding how variation impacts a multibody dynamic (MBD) system's response is important to ensure the robustness of a system. However, how the variation propagates into the MBD system is complicated because MBD systems ...
