Purpose of the study. The study's aim was to examine how reactive stress tolerance differs in preadolescence across six different non-contact sports.Materials and Methods. Archery, cycling, shooting, swimming, track & field, and weightliftin... see more

A significant share of structures includes the components that are in contact with each other. These include, for example, stamps, molds, machine tools, technological equipment, engines, etc. They are characterized by a varied load mode. Therefore, an imp... see more

The stresses induced by a mechanical contact imposed on a birefringent sphere have been studied experimentally and numerically. The birefringent sphere is machined from a birefringent parallelepiped on a high speed numerically controlled machine. The resi... see more

When justifying the design parameters, it is necessary to carry out the analysis of the strain-strain state of individual elements of technological systems, which are sets of parts under contact interaction conditions. These problems are nonlinear, and th... see more

Gears is a rotating cylindrical wheel having tooth cut on it and which meshes with another toothed part to transmit the power or torque.. In this investigation, at first, bending stress and contact stress between sun gear and planet gear tooth were determ... see more

Purpose. In the research one should do: 1) to determine a 3-d stress-strain state of the rail head in contact with the rolling wheels; 2) to analyze different forms of contact interaction; 3) to obtain the data necessary to calculate the durability of rai... see more

Solution of the axis-symmetric contact task of thermo-elasticity of the hot cylinder circular punch stress on the elastic isotropic layer taking into account a non-ideal heat contact between punch and layer is built. Formulas for determination of the temp... see more

The stresses induced by a mechanical contact imposed on a birefringent sphere have been studied experimentally and numerically. The birefringent sphere is machined from a birefringent parallelepiped on a high speed numerically controlled machine. The resi... see more

Conventionally discussed dynamic mechanisms of elastic strain energy redistribution in near-contact surface regions include P and S elastic wave pulses radiating from the contact surface. At the same time, the elastic strain energy can be transferred by l... see more
