The discussion revolves around calculating shear stress in stainless steel and other materials, specifically focusing on yield strength and its application to rods and shafts of varying dimensions.
Some participants provide insights into the definitions of yield strength and stress, while others raise questions about the applicability of general values to specific cases. There is an ongoing exploration of material properties and their implications for stress calculations.
Participants note potential confusion regarding the source of yield strength values and whether they are based on standard shapes or specific dimensions. There is also mention of the need for material properties specific to stainless steel and alloy steels.
You should be given this value, or you can look it up somewhere. Tensile and shear yield strengths are a function of the material properties. For alloy carbon steels, the shear yield stress is aproximately the tensile yield stress divided by the square root of 3. I am not sure if this relationship holds for stainless steel alloys.nileshrathod said:how i can work out the maximum shear stress of 80 mm diameter solid shaft of en 19 alloy steel? i need this in order to work out the minimum shaft diameter that will capable of withstanding the torque applied to it.
