the available methods for predicting mechanical characteristics of pavement layers are categorized into two general groups, destructive and non-destructive. in destructive method, using coring and pavement subgrade and performing necessary experiments on them, the quantities of layers properties will be identified. in non-destructive method, the attained deflection is measured by applying the l...

A new nite element method for elliptic problems with locally periodic microstructure of length " > 0 is developed and analyzed. It is shown that the method converges, as " ! 0, to the solution of the homogenized problem with optimal order in " and exponentially in the number of degrees of freedom independent of " > 0. The computational work of the method is bounded independently of ". Numerical...

Thermo-hyperelastic problems at finite strains belong to a category of non-linear coupled problems that impose challenges on their numerical treatment. We present the weak-form for a 1-D coupled, stationary, thermo-hyperelastic system with constant or temperature-dependent material properties. The coupled system is discretized by a ‘monolithic’ high-order finite element method (p-FEM) based on ...

the dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. however, the mechanical behavior of rubber parts is highly temperature dependent. in most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

Abstract A Problem Solving Environment for the finite element method (FEM-PSE) is an application system to support users pursuing a career in the finite element analysis (FEA). There are two types of users associated with the FEA. One is analysis-user who uses application software of the FEM and the other is development-user who develops application software of the FEM. We used an abstraction t...

the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...

A selective smoothed finite element method (Selective S-FEM) is developed for dynamic 3D analysis of extremely large deformation of incompressible bio-tissues, using the simplest 4-node tetrahedron elements. In the present selective S-FEM, face-based Smoothed FEM (FS-FEM) and node-based Smoothed FEM (NS-FEM) are, respectively, used for the deviatoric and volumetric parts of the deformation of i...

Isogeometric analysis, as a special field of the finite element method (FEM) which integrates geometric and finite element mesh modelling, is one of the promising directions of FEM development. The paper presents a concept of isogeometric FEM analysis of thin-walled structures based on the Kirchhoff-Love shell formulation and NURBS as basis functions. The basic properties of isogeometric shell ...
