A self-built laser projection system for optical transverse strain measurements in tensile testing is presented. The setup based on diode modules, charge-coupled device array detectors, and standard optomechanical components proposed to be a low-cost polymer samples. mobile can easily mounted test machine. Circular cross-sectional changes diameter were detected with 10-μm resolution stress-stra...

This paper presents quantitative estimates of the strain rates for southern part Siberian craton derived from GPS data. The obtained results confirmed theoretical concept low (10 –9 ×year –1 ) in intra-platform areas. is based on raw measurement data open sources, previously reported displacement velocities, and Laboratory Recent Geodynamics Institute Earth's Crust SB RAS. It shown that 5 menti...
