Tensile stress of the material
Thread Content
Does anyone know what tensile stress in materials is? Was this data obtained through research, calculation, or experimental measurement? Where can I look this up? Where are the formulas I can use to calculate it? I would appreciate it if the teachers could give me some guidance. Thank you. reward_7ree
Normal stress (tensile stress) is the intensity of the internal force distribution on the cross-section of a member, and is referred to as stress. Stress is the intensity of internal forces at a certain point on a cross-section of a stressed member. (The above is excerpted from Mechanics of Materials 1, 4th edition, by Sun Xunfang.) The stress component perpendicular to the cross-section is called normal stress (or normal stress, denoted by σ) ； The stress component tangent to the cross-section is called shear stress, denoted by τ. The unit of stress is Pa. 1 Pa = 1 N/m2. In engineering practice, stress values are often quite large, so MPa or GPa are used as units. 1 MPa = 106 Pa (10 to the sixth power), and 1 GPa = 109 Pa (10 to the ninth power)
Tensile stress is the same as normal stress, right? There are two types of stress: normal stress (tensile or compressive stress) and shear stress. The formula for calculating stress was already provided above. You can study mechanics of materials. Material standards provide information on the yield strength and tensile strength of different materials; for example, GB713 and similar standards. GB150 gives details regarding the allowable stress for materials, with the allowable stress being equal to the yield strength or tensile strength divided by a safety factor
