[en] Ti6Al4V is an hcp material that exhibits a strain rate sensitive behaviour and the tension
compression asymmetry yielding known as the Strength Differential (SD). To quantify the SD effect
of this alloys, initial yield compressive stress at different temperatures are computed by performing
two type of tests, the conventional constant die speed and the constant strain rate compression tests.
