This paper studies mixed finite element approximations of the viscosity solution to the Dirichlet problem for the fully nonlinear Monge–Ampère equation det (D²u⁰) = f (> 0) based on the vanishing ...

A few guidelines show how to correctly use FEA stresses to find reasonable margins of safety. Although finite-element analysis has become an indispensable part of engineering, a few users knock it ...

Adaptive remeshing for Abaqus Standard lets the software remesh and rerun a simulation to reduce meshdependent displacement, stress, or strain errors. Substructuring is an add-on that calculates ...

Sometimes, it’s easy for a computer to predict the future. Simple phenomena, such as how sap flows down a tree trunk, are straightforward and can be captured in a few lines of code using what ...

We study a nonlinear elliptic equation with measurable nonlinearity in a nonsmooth domain when the righthand side is a measure. A global Calderón-Zygmund type estimate in variable exponent spaces is ...
