The finite element method (FEM) is a well known numerical method in solving partial differential equations (PDEs). All numerical methods inherently have error in comparison to the true solution of the PDE. Base on the FEM theory, the appropriate norm of this error is bounded and it can be estimated by the mesh size. One standard method to get an idea about the sensibility of the numerical solut...

We present a novel compression algorithm for 2D scientific data and images based on exponentially-convergent adaptive higher-order finite element methods (FEM). So far, FEM has been used mainly for the solution of partial differential equations (PDE), but we show that it can be applied to data and image compression easily. The adaptive compression algorithm is trivial compared to adaptive FEM a...

This study is the first report of numerical solution of nonlinear bending analysis for annular and circular plates based on 3D elasticity theory with asymmetric boundary conditions using semi-analytical polynomial method (SAPM). Orthotropic annular and circular plates are subjected to transverse loading and 3D bending analysis in the presence of symmetric and asymmetric boundary conditions is s...

A. Śliwa, M. Bonek, Silesian University of Technology, Institute of Engineering Materials and Biomaterials, Gliwice, Poland Investigations include FEM simulation model of alloying the PMHSS6-5-3 steel surface layer with the carbides and ceramic powders, especially WC, VC, TiC, SiC, Si3N4 and Al2O3 particles using the high power diode laser (HPDL). The FEM computations were performed using ANSYS...

Due to concerns over particle generation in conventional metal-on-polyethylene hip bearings used in total hip arthroplasty (THA), interest in advanced low-wear bearing alternatives such as ceramic-on-ceramic (CoC) couples has reemerged. While ceramics demonstrate excellent compressive strength, the brittle nature of the material reduces tensile strength, possibly leading to catastrophic fractur...

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...

Non-linear numerical modeling, widely used in research and development to understand many complex processes such as forming or machining, does not guarantee the success of a study be performed. Indeed, simulation uses finite element codes where models already integrated are based on shapes adjustable any type study. In this study, new form non-linear constitutive flow law Modified Zerilli-Armst...

The application of the elasto-plastic material model known as Barcelona Model (BM) for numerical assessment a historical vault subjected to earthquake sequence is presented in this work. As case study, part masonry erected Southern Poland 12th century was chosen. For study purposes, 3D finite element (FEM) prepared using ABAQUS/Standard software program. essential details structure geometry wer...

Abstract Manufacturing processes, such as machining, can produce residual stresses in products. Residual stress and its distribution be the main factor influencing fatigue life of machined components has already been subject many experimental numerical studies. The high-temperature condition, a result makes change microstructural properties material consequently affect mechanical workpiece. A m...

In the last few years, demand for hot stamped components has increased in automotive industry. Determination of formability under stamping is challenging due to elevated temperature, fast cooling, and high punch velocity. Although there was various strive determination, but were limitations with experiments like non-uniform heating specimen, strain, temperature distribution. Therefore, this wor...
