Mortars have been widely used even in prehistoric periods in making pavements in open areas or floors inside dwellings. They are found as surface layers well-compacted an [...]

Abstrakt:

Cement paste is the important component of other engineering heterogeneous materials, such as various kinds of concrete. Using the micromechanic approach, intrinsic elast [...]

Recently, several collapses of assembled floors with large clay units took place in the Czech Republic. The failures are occurring in certain period after finishing of co [...]

The masonry constructions are widely used for a long time. Nowadays, new masonry structures are on demand owing to its variety and appealing mechanical properties. Both b [...]

Mechanical stimuli represent a very important factor influencing cellular processes and functions. The knowledge about mechanical properties of cells is necessary for und [...]

Concrete is represented as a two-phase material in this paper. Behaviour of a crack with its tip on the interface between two different materials - hardened cement paste [...]

The current distribution over the plate surface in lead-acid cells was determined mathematically by using the equivalent circuit method. The dependence of the internal ce [...]

The current distribution over the plate surface in lead-acid cells in the course of discharge was determined mathematically by using the equivalent circuit method. The de [...]

It is well established that most construction materials behave differently under static and dynamic loading. The stress-rate sensitivity of concrete, steel and rock has b [...]

The paper deals with the perfusion in hierarchically arranged double porous media constituted by transversely periodic layers. In each layer the reference periodic cell i [...]

Instable behaviour both of the road and tram bridge at the Prague “Chotkova road” up to Klárov and the rock mass around has been monitored long time yet. The movemen [...]

The paper aims to evaluate effective properties of a solid phase of metal foam on the level of a few microns. Basic principles of micromechanics are applied to the experi [...]

The purpose of this contribution is to introduce a comparison of two Finite Element-based methods for computing the mechanical response to (thermo)mechanical loading of c [...]

Abstrakt: The stepping stone in evaluating effective elastic properties of woven composite tubes is an accurate geometrical description of the composite tube on meso-scal [...]

A two-layer statistically equivalent periodic unit cell with air voids is offered to predict a macroscopic response of plain weave multilayer textile composites. Two diff [...]

Homogenization methods are becoming the most popular approach to modelling of heterogeneous materials. The main principle is to represent the heterogeneous microstructure [...]

The paper offers a novel approach to the modeling of asphalt mixtures. It introduces a concept of so called statistically equivalent periodic unit cell (SECUP) known from [...]

This contribution deals with problem of solids weakened by cracks or joints. The rock containing crack is the model example of such a problem. Determination of properties [...]
