STRESSDOE-HDBK-1017/1-93Properties of MetalsThe important information in this chapter is summarized below.Stress is the internal resistance of a material to the distorting effects of anexternal force or load. Stress s FAThree types of stressTensile stress is the type of stress in which the two sections of materialon either side of a stress plane tend to pull apart or elongate.Compressive stress is the reverse of tensile stress. Adjacent parts of thematerial tend to press against each other.Shear stress exists when two parts of a material tend to slide across eachother upon application of force parallel to that plane.Compressibility is the ability of a material to react to compressive stress orpressure.MS-02Page 6Rev. 0
