TRANSVERSE  TESTS  OF  LAMINATED  BEAMS  UNDER  STATIC  AND  DYNAMIC  LOADS

The paper presents the results of transverse bending tests of laminated beams under static and dynamic loads. While conducting transverse tests for four laminated beam specimens under a static load, fracture load, fracture pattern, relative and absolute deformations were detected. The bending-load dependence was plotted. While conducting transverse tests for five laminated beam specimens under a dynamic load, time dependencies for the following parameters were plotted: load, acceleration, velocity, and bending. The dynamic factor was detected experimentally.

Keywords: transverse test; dynamic load; eigen frequency; laminated beams; dynamic factor.
