Effect of Combined Laser Thermal and Shock Wave Effects on the Mechanical and Tribological Properties of Steels.

Herein, we present the results of an experimental study on the mechanical properties of Fe-C alloys with different carbon contents (0.2, 0.45, and 0.

Identification of Dynamic Behavior Models of Concrete B22.5.

We discuss experimental and numerical studies of the deformation and destruction of fine-grained concrete B22.5 under dynamic loading. The experiments were carried out using the Kolsky (or split-Hopkinson pressure bar) method, and its modifications in the strain rate range from 400 to 2000 s.

The Influence of Specimen Geometry and Loading Conditions on the Mechanical Properties of Porous Brittle Media.

Dynamic tests of fine-grained fired dioxide-zirconia ceramics under compression under uniaxial stress conditions were carried out. The influence of the specimen length on the obtained strength and deformation properties of ceramics is investigated. The thickness of the specimen has a significant impact on the course of the obtained dynamic stress-strain diagrams: short specimens have a much more sloping area of active loading branch.

Dynamic Testing of Lime-Tree () and Pine () for Wood Model Identification.

The paper presents the results of dynamic testing of two wood species: lime-tree () and pine (). The dynamic compressive tests were carried out using the traditional Kolsky method in compression tests. The Kolsky method was modified for testing the specimen in a rigid limiting holder.
