Analyses of dynamic responses are significantly important for the design, maintenance and rehabilitation of asphalt pavement. In order to evaluate the dynamic responses of asphalt pavement under moving loads, a specific computational program, SAFEM, was developed based on a semi-analytical finite element method. This method is three-dimensional and only requires a two-dimensional FE discretizat...

The paper presents a simple but efficient new numerical scheme for the integration of nonlinear constitutive equations. Although it can be used for integration of system of algebraic and differential equations in general, the scheme is primarily developed for use with direct solution methods for solving boundary value problems, e.g. explicit dynamic analysis in ABAQUS/Explicit. In the developed...

Soils are mixtures of three phases, a porous soil skeleton of solid mineral particles and two fluids water and air filling the pores completely. The soil skeleton and the fluids can move depending on the constitutive behaviour of all constituents and interactions between them. In general a coupled deformation/seepage problem exists which can be uncoupled for certain circumstances. Mechanical mo...

Steel plate shear walls (SPSW) have been used as the primary lateral force resisting system in buildings. Extensive analytical studies on steel plate shear walls in the United States, Canada, Taiwan and other countries have already validated the simple analytical model known as strip model to predict the monotonic behavior of this kind of structural system. However, more research is still neede...

Flexible printed circuits (FPC) are widely used in various electronic packages to interconnect high-performance devices. In case of dynamic applications mechanical reliability of FPCs is becoming a serious issue as complexity of the devices grows and miniaturization trend continues. For many of such applications, failures of FPCs can lead to serious consequences. Fatigue data on FPCs are not co...

Concrete is a versatile material having number of desirable properties, so widely preferred in construction industry. But major disadvantage that under severe vibrations such as earthquakes it gets cracked and concrete has poor modification repair quality. Therefore some or strengthening must be performed damaged element stand for further useful life. Many civil structures are no longer conside...
