The engineering stress-strain curve in shear is the same as the true stress-strain curve because, in shear, the definitions of stress and strain do not change significantly with the material's deformation. True stress accounts for the instantaneous area under load, while engineering stress uses the original area; however, in shear, the relationship remains linear up to the yield point, and the area reduction effect is minimal for typical shear tests. Thus, both curves reflect the same material behavior in shear deformation, leading to equivalent representations.
Concrete's best strength rating is in compression, as in equal force from either side. Its weakest rating is in its shear strength, as in force in different areas like snapping a pencil in your hands. To increase concretes shear strength, re-inforcing steel bar is used because of its high shear strength characteristics.
The modulus of rigidity, or shear modulus, is not typically considered in shear tests because these tests primarily focus on determining the material's shear strength and behavior under shear loading. Shear tests, such as the torsion test or direct shear test, measure how materials deform and fail under shear stresses, rather than quantifying their elastic properties. While the shear modulus can be derived from the initial linear portion of the stress-strain curve in some tests, the main objective is to evaluate the material's performance and failure characteristics under shear conditions.
the average shear stress is 3/4 the maximum shear stress for a circular section
The correct term is "shear tensile strength." This term refers to the material's ability to withstand shear stresses before failure, particularly in situations where tensile forces are also acting. "Tensile shear strength" is less commonly used and may cause confusion, as it implies a different relationship between tensile and shear stresses.

The shear modulus of a material is calculated by dividing the shear stress by the shear strain. This can be represented by the equation: Shear Modulus Shear Stress / Shear Strain.

Shear Stress divided by the Angle of Shear is equals to Shear Stress divided by Shear Strain which is also equals to a constant value known as the Shear Modulus. Shear Modulus is determined by the material of the object.
