Stress:strain materials testing instrument

A grip for a material testing load frame including a grip plate for engaging the end of an elongated sample having a longitudinal axis and a grip body having one end for connecting to the grip plate and another end for connecting to a loading component of the frame, a mechanism for adjusting the concentricity of the plate with respect to the body, and a mechanism for adjusting the angle of the plate with respect to the body, so that when the sample end is engaged by the plate, and the grip body is connected to the loading component, the longitudinal axis and the axis of the loading component can be aligned with respect to the concentricity and angle.
