In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component (e.g. beams, plates, or bolts). In a reinforced concrete beam, the main purpose of reinforcing bar (rebar) stirrups is to increase the shear strength.
A bolt with property class 12.9 has a tensile strength of 1200 MPa (1 MPa = 1 N/mm 2) or 1.2 kN/mm 2 and the yield strength is 0.90 times tensile strength, 1080 MPa in this case. A bolt with property class 4.6 has a tensile strength of 400 MPa (1 MPa = 1 N/mm 2) or 0.4 kN/mm 2 and yield strength is 0.60 times tensile strength, 240 MPa in this case.
Shear stress (often denoted by τ, Greek: tau) is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts.
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from ⁄ to 1⁄ inches (13 to 38 mm) in diameter. [1]
Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) [1] is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials, the ultimate tensile strength is close to the yield point, whereas in ductile materials, the ultimate tensile strength ...
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
