Statistical Volume Elements for the Characterization of Angle-Dependent Fracture Strengths in Anisotropic Microcracked Materials
(The American Society of Mechanical Engineers (ASME), 2020)Statistical volume elements (SVEs) are used to homogenize fracture strength of rock, based on the microcrack statistics of a real-world Yuen-Long marble sample. The small size of SVEs enables maintaining inhomogeneities ... -
Parameter Estimation of Limited Failure Population Model With a Weibull Underlying Distribution
(The American Society of Mechanical Engineers (ASME), 2020)For many data-driven reliability problems, the population is not homogeneous; i.e., its statistics are not described by a unimodal distribution. Also, the interval of observation may not be long enough to capture the failure ... -
Design for Interface Stiffness of Mechanical Products Using Integrated Simulation and Optimization Under Uncertainty
