Structural Vulnerability of Coastal Bridges Under Hurricane Conditions
… parameters (mass scaling factor, damping hourglass control, displacement hourglass scaling factor, and bulk viscosity scaling factors) and configurations (mesh size) and to determine optimal filter designs. This work resulted in recommendations for conducting numerical analyses, …

A Mesh Objective Algorithm for Modeling Mode-I Cracks Using a Standard Finite Element Formulation
… of crack segments to define the crack path. An hourglass control method is developed for an element undergoing softening. The tangent crack stiffness is used to derive hourglass forces that help obtain mesh objectivity when one-point quadrature is applied. Finally, a cross-over scaling method is …
