The maximum allowable stress in steel (under tension as well as shear) can be calculated easily and most accurately by using Nori Design Formulae. These Design Formulae, developed by Nori VSN Murthy, are applicable for design engineering activity of all mechanical and structural engineering work ranging from a safety-pin to spacecraft. By all means, Nori Design Formulae are the greatest gift to our rapidly changing technological world. These formulae can be obtained through ASM International-USA.
The maximum allowable stress for a given steel (under tension as well as shear) can be calculated easily and most accurately by using Nori Design Formulae. By all means, Nori Design Formulae propounded by Nori VSN Murthy are the greatest gift to our rapidly advancing technological world crippling with debatable safety margins (factor of safety) that are varying from source to source and also from time to time.
Most importantly, Nori Design Formulae are applicable for the entire design engineering activity ranging from a safety-pin to spacecraft. Our world has been eagerly waiting for these priceless formulae ever since the birth of machines on earth.
Interestingly, Nori Design Formulae offer numerous other in-built and spin-off benefits too. Most essentially, Nori Design Formulae will provide a fundamental methodology, hither-to-unavailable, for precise evaluation of steels and, supports development of cost-effective, strength-effective and weight-effective steels most needed for lighter weight, longer life, smaller size, higher reliability, enhanced safety and lower cost.
Ultimate shear stress of Mild steel is 210N/sq mm
66N/Sq.MM in varying condition and 100 N/Sq. MM in Steady condition for mild steel as per cmti hand book pg. 685
You may increase the slab thickness and/or calculate the steel reinforcement required to withstand against the applied shear stress.
Allowable stress would normally refer to design using Allowable Strength Design, also known as working strength design. In this the allowable stress is usually a fraction of the yield strength and can be different for uniform tension and bending. Typically mild steel has a yield strength of about fy=250MPa with allowable stresses in Tension, 0.6fy=150MPa Bending, 0.66fy=165MPa
the average shear stress is 3/4 the maximum shear stress for a circular section
Ultimate shear stress of Mild steel is 210N/sq mm
ther are so many varieties of mild steel to answer specifically. For most all steels, the shear yield is 0.577 times the tensile yield ( that is tensile yield divided by square root of 3) So if a mild structural steel has a tensile yield of 36,000 psi, its shear yield is 0.577(36000) = 21,000 psi
shear = 77GPa
Shear modulus or Rigidity modulus:For material subjected to shear, Within the elastic limit, the shear stress is proportional to the shear strain.The value of Modulus of rigidity for steel is 80 - 100KN/mm^2

Compressive Stress for mild steel (IS 2062 Gr.B - ASME SA 36 is 407.7 MPa This is what I think is the value. If there are different valuses please send me a amil. ramsrini16@yahoo.com Dr.S.RAmachandran, NIOT , Chennai.
generally, it was used to shear mild steel, stainless steel,metal plate. more info, you can see our web www.shearingmachine.org,we are a manufacturer fromChina
Mild steel tensile stress of 370 to 520 Newtons per square millimeter.
During a tensile test of mild steel, the bar is tested until it breaks. It measures how much stress the mild steel can take before it finally breaks under the pressure.
