Constancy of the Tensile Test Machine Stiffness

CODEN: JTEVAB

Abstract

A method is presented for determining the current value of the stiffness of a tensile machine during uniaxial loading tests. The method is based on stress relaxation tests and on the measurement of the slopes of the load-time curve at the moment when the crosshead speed is changed from zero to some finite value. This method has shown that the stiffness can be taken as a constant within fairly wide ranges of the load level, crosshead speed, and specimen dimensions.
