The purpose of the paper is to discuss the hardening problems in materials. Kinematic and isotropic hardening are considered. The paper has a review character.
In this paper the results of investigations on buildings heat gains components are introduced. The factors, which influence heat gains in analysed building were identified. The changes of value of these quantities on the influence of individual factors were estimated.
This study presents opportunities and potential of solar energy and tendencies of its use. The EU climate package of "3 x 20%", and a new directive of EU about promotion of renewable sources of energy create perfect conditions for fast development of modern technologies in solar energy sector. Evolution of use of solar energy in Poland points to huge potential which cannot be neglected.
The purpose of the paper is to analyze deformation problems in welded structures. The stresses resulting from thermomechanical loadings cause bending, buckling and rotation. The basic types of distortions in welding are analyzed. The paper has a review character.
The purpose of the paper is to compare two basic yield criteria met in engineering mechanics i.e. Huber-Mises and Treska. The various forms of the yield locus are presented and discussed. The paper has a review character.
The article contains the theoretical bases of the analyses process floating causes and grinding concrete surface. The particular attention has been paid to quality factors of processing determined by roughness uniformity of processed surface.
This is an analysis of the influence of the changes in the overburden rigidity on the alteration of the radius of the main influence range and the changes of the main influence range angle in a rock mass as parameters of the theory of forecasting the influence of mining on the surface and rock mass. The results obtained justify the view that in order to forecast the value of the terrain and rock mass...
The Cukurova Delta represents internationally important coastal strip ecosystems and is located in the south-eastern part of the Mediterranean Sea in Adana city, Turkey. The Delta includes the largest natural sand dune ecosystems in the country; therefore, it contains valuable habitats of many species e.g. water birds and internationally threatened sea turtles. Unfortunately, the biodiversity of the...
The article presents the methodology of approach to the optimization of the geometrical form of a disk-type element for the treatment of surface by grinding, lapping, etc.
The development of architecture of bridges in conformity with change of architecturally-art styles is show in this paper. A brief analytical overview of the history of bridges building is made, methods for constructing three-dimensional composition are considered, the interrelation of constructions and materials with the architectural form of bridges is shown.
The paper describes the mathematic model for calculating glass sheets loads taking into consideration the cooperation of the gas layer sealed in the hermetic gas space of an complex glass panel. In loaded glass unit, the gas coupling of loads takes place. By means of numbers it is expressed by the gas pressure change in the gas space of a loaded glass sheet in relation to the initial pressure assumed...
