The results of experimental study of mechanical properties of samples of lime-sand brick under dynamic loading are presented. The tests were carried out using the traditional Kolsky method and its modification - dynamic splitting (the so-called «Brazilian test»). The laws of change in strength, strain, time properties and energy intensity of the investigated material are established in the strain rate range of 5·102-2.5·103 s-1 under compression and in the stress rate range of 2·101-3·102 GPa/s under tension.

There are described properties of hardening multi-functional silicate composite during its long-term dynamical loading in the paper. Studied composite was developed for special application in permanent way structure in Prague underground. Dynamic loading was carried out on the laboratory model, in which the composite was applied as a bench of the rail anchoring. Due to loading in early ages was also studied the option of steel fibers addition. Results obtained confirmed impressive potential for practical use during new tracks construction, and quick repairs as well, because of rapid evolution of mechanical properties and sufficient resistance to dynamic loading. Silicate composite with fibers addition had better mechanical properties, however significant improvement during dynamic loading was not recorded in comparison with the reference mixture without fibers. Generally, new composite material confirmed great potential for practical use in transportation industry.

During operation the technological pipelines of gas-distributing station are affected by mechanical static loading resulted from internal pressure of gas in the high pressure pipelines and a dynamic loading from a high-speed stream of gas in low pressure pipelines. A comparison is made of characteristics of mechanical properties of gas-distributing station pipes metal after a long-term operation for the conditions of static and dynamic loading effects.

High reinforcement content TiB2/2024Al composites (Vp=55, 65%) were fabricated by squeeze casting technology, and their microstructures as well as mechanical properties under quasi-static and dynamic loading were evaluated. For 55 vol.% TiB2/Al composite, the bending strength and elastic modulus were as high as 623.5MPa and 218.1GPa. When compressed at a strain rate of 1050s-1, both composites exhibited a higher compressive flow stresses and compressive moduli than those under quasi-static loading. The micro-damage of high reinforcement content composites was mostly dominated by the large particle cracking. In addition, some evidence of aluminum alloy melting was observed on the fracture surfaces of dynamic compression, it was ascribed to the adiabatic heat accumulated in a local region transferred by plastic work.
