Originální abstrakt

Dynamic Young´s modulus of elasticity can be determined by ultrasonic pulse method and resonance method. Because of the difference in the way of introducing tension into a test specimen, the values of modulus of elasticity differ. Dynamic Young´s modulus of elasticity measured by ultrasonic pulse method is higher; the difference stated for concrete is 5 to 20%. It was found that the dynamic Young's modulus of elasticity of calcium silicate bricks and prisms measured by ultrasonic pulse method is on average higher by 9.5% than dynamic Young's modulus of elasticity measured by resonance method. If dynamic Young's modulus of elasticity is converted to static modulus of elasticity, this difference has to be taken into account by means of appropriate coefficient.
