This review presents developments in structural shape optimization post 2000 from
perspective of numerical analysis techniques. Traditional shape optimization with FEM has …

This paper presents an overview of the Trefftz finite element and its application in various
engineering problems. Basic concepts of the Trefftz method are discussed, such as T …

The goal of this study is to obtain globally optimum shapes for two-dimensional structures
subject to quasi-static loads and restraints. For this purpose a technique is proposed, using …

Fillets are usually the most critical regions in mechanical parts especially under fatigue
loading, considering that an increase in the maximum stress level considerably shortens the …

The elastodynamic response of saturated poroelastic media is modelled approximating
independently the solid and seepage displacements in the domain and the force and …

The equations that govern the dynamic response of saturated porous media are first
discretized in time to define the boundary value problem that supports the formulation of the …

An adaptive p-refinement procedure for the implementation of the displacement model of the
hybrid-Trefftz finite element formulation is presented. The procedure is designed to select …

The stress and displacement models of the hybrid-Trefftz finite element formulation are
applied to the solution of incompressible axisymmetric saturated porous media. The use of a …

The hybrid-Trefftz formulation of the finite element method is applied to the transient,
physically and geometrically linear analysis of incompressible saturated porous media. Two …

The tie rod shaft is one of the most essential parts in the coal grinder machine at the coal mill
plant to support the roller grinder axial movement. Since the tie rod shaft receives the cyclic …
