Abstract: Explicit dynamic analysis has proven to be advantageous when simulating shock and impact loading, and very small time-scale events. In this article, the feasibility of using a background mesh of B-spline elements for ...

Abstract: A sequential approximation algorithm is presented here that is particularly suited for problems in engineering design and structural optimization, where the number of variables is very large and ...

Abstract: Optimal layouts for structural design have been generated using topology optimization approach with a wide variety of objectives and constraints. Minimization of compliance is the most common objective but the resultant ...

Abstract: Mesh generation for traditional finite element analysis has proven to be very difficult to fully automate especially using hexahedral elements for complex 3D geometry. Several modifications to the finite element method ...

Abstract: A layered manufacturing technique that uses electrophotography is described where powder is picked up and deposited using a charged photoconducting surface and deposited layer by layer on a build ...

Abstract: Single crystals of NiAl are very ductile at intermediate temperatures (400–700 K) and were observed to exhibit high strain hardening rates at large strains when loaded in the [110] orientation. ...

Abstract: Numerical methods for solving boundary value problems that do not require generation of mesh to approximate the analysis domain have been referred to as mesh-free methods. While many of these ...

Abstract: A method to estimate the resistivity of composite structures using an inverse problem solving algorithm is presented that uses voltage distribution on the structure as data. Electrodes attached ...

Abstract: Deformation of NiAl single crystals was studied using finite element analysis to investigate the modes of localized deformation. Constitutive parameters and hardening characteristics of the active ...

Abstract: A method for finite element analysis using a regular or structured grid is described that eliminates the need for generating conforming mesh for the geometry. The geometry of the domain is ...
