Computerized test stand for research of strain waves in composite constructions

The paper presents a test stand for investigation of composite constructions such as beams and plates to be shock loaded by a striker with piezoelectric force transducer. Velocity of the striker is up to 40 mps. Measurements results are acquired by a computerized measurement system. Experimental results of contact shock force acquisition are stated with following calculations of non-stationary bending and shearing strain waves in glass-fiber-reinforced plastic beams and plates.
