Since the action modes of load include tension, compression, bending, shear and other forms, the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so . For the application in the tension-braced pressure vessel, liner materials with the lowest possible modulus should be used to reduce the stress peaks in the liner. Metal strength refers to the ability of metal materials to resist permanent deformation and fracture under the action of external force. Bronzes (sometimes called phosphor bronzes) are alloys of copper and tin. . However, its strength will decline to below 400 MPa when the temperature is over 550 • C [2, 3]. Meliodent denture base showed adhesive, cohesive, and mixed failure, while all Eclipse showed adhesive failure with various reline materials.
