The implementation of a new 8-node finite element for solving 3D elasticity static problems is considered. idea this based on the projection rare mesh FEM scheme into space lower dimension. resulting hexahedral has number features compared to classical polyline element. This one integration point in eight element, as well presence four parameters that allow you adjust convergence computational ...

The present study presents a new methodology developed for an analytical model of a composite fuselage. It also presents finite element analyses of a simplified model and comparisons with more complete models. These comparisons show that there is a very good correlation between both models for the cases studied. Therefore, the applicabilty of the proposed procedure was demonstrated. Based on fi...

The fabrication route for tidal turbine blades has been compounded with the appearance of additive manufacturing; use infill patterns, improvement mechanical strength and material reduction 3D printed parts can be obtained. Through finite element analysis three-point bend tests, optimal lattice pattern, viability shell–infill blade model as an alternative to conventional shell-spar was determin...

Shear-wave vibrator is a type of equipment usually employed for natural gas exploration, consisting vibrating machine which applies dynamic loads to the surrounding soils in order ease extraction gas. Detailed numerical simulations these devices are scarce literature. Thus, this paper, nonlinear 3D finite element simulation has been conducted investigate main features response vibrator. Nonline...
