Abstract: A direct continuum approach for shape‐design sensitivity of three‐dimensional elastic components is presented. By analyzing the shape‐design perturbation process, the shape change can be represented by a boundary loading ...

Abstract: A neural network-based design system is presented in this paper for preliminary design of concrete box girder bridges. The system is based on a loose coupling model that integrates the artificial neural network and the ...

Abstract: The response of a blast mitigation cladding consisting of a face sheet and metal foam core subjected to a close-range blast is predicted. Whereas the cladding is sufficiently wide compared to the standoff distance between ...

Abstract: Nodal variable-based discontinuous deformation analysis (NDDA), which couples the finite-element method (FEM) mesh inside a discontinuous deformation analysis (DDA) block, aims to improve the stress accuracy and the contact ...
