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

Draw stress strain curve for mild steel?

Mild steel usually contains predominantly of Ferrite structure and it has got good ductility. The difference in stress-strain curve of Mild steel to other ductile materials is that it undergoes Multiple yielding. it occurs due to the fact that C and N segregate to dislocations.


What is the tensile strength of mild steel?

Mild steel is a fairly general classification and can cover a considerable variation in material properties. Cold drawn grades in particular will have a higher tensile strength than hot rolled. Something like 400 MPa for yield stress and 500 MPa for ultimate tensile strength is quite common.


What is the fracture toughness of mild steel?

The fracture toughness, or the property that describes the ability of a material containing a crack to resist fracture, of mild steel is around 50 K (where 'K' is the stress intensity factor).
