An example of the experimental validation of a finite element model of a selected heavy vehicle is presented in the paper. A truck tractor with a three a xle single drop low boy trailer and the total weight of 20 t ons was selected as a representative for the tests. The major goal of the conducted studies w as to develop a well validated the numerical model of a heavy vehicle applicable for com...

This report presents a formal approach for optimizing the shape of freely supported isotropic plates to withstand air blast loading. Unique difficulties are presented by the nature of shortduration dynamic loading, viz. transient dynamic response, monitoring of maximum plastic strain failure at every point in the panel over time, optimizers that can handle non-differentiable, nonconvex and comp...

Using the highly recommended numerical techniques, a finite element computer code is developed to analyse the steady incompressible, laminar and turbulent flows in 2-D domains with complex geometry. The Petrov-Galerkin finite element formulation is adopted to avoid numerical oscillations. Turbulence is modeled using the two equation k-ω model. The discretized equations are written in the form o...

This paper presents thermal buckling analysis of rectangular functionally graded plates (FG plates) with an eccentrically located elliptic cutout. The plate governing equations derived by the first order shear deformation theory (FSDT) and finite element formulation is developed to analyze the plate behavior subjected to a uniform temperature rise across plate thickness. It is assumed that the ...

This paper provides an incremental layerwise finite element formulation for the viscoelastic analysis of multilayered pavements.  The constitutive behavior of asphalt concrete is represented by the Prony series. Layerwise finite element has been shown to provide an efficient and accurate tool for the numerical simulation of laminated structures. Most of the previous research on numerical simula...

Abstract Titanium alloy is an advanced lightweight armor material, widely used in armored vehicles. Experimental and simulation investigations on perforation of titanium plates impacted by armor-piercing projectiles were performed this study. The critical ricochet angle failure morphology 6 mm, 8 10 mm 12 subjected to obtained. Simultaneously, Numerical simulations the oblique then high-perform...

Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...
