Different workpiece materials display different combinations of shear strength and ductility. The ductility of a workpiece material is the extent to which it can be deformed until it shears off (see Figure 2).
Different types of steel beams can also be assembled by welding separate structural steel plates together. In this way, each flange is attached to the web separately. Welding can decrease the weight of the beam, and add strength. This is how plate girders are made. They are welded, bolted ...
Comic-book superheroes are sometimes able to punch holes through steel walls. If the ultimate shear strength of steel is taken to be 2.90 x 109 Pa, what force is required to punch through a steel plat Prove that elastic energy density is (1/2) stress times strain. ...
A strain is a dimensionless quantity and is usually expressed in percentages. Typical measures for strain are less than 2 mm/m for steel and are often expressed in micro-strain units. One microstrain is the strain producing deformation of one part per million. The abbreviation for microstrain is...
What is the young's modulus of ASTM A992 steel? Any difference between Young's modulus and yield strength? What is the charge's SI unit? What is the unit of sqrt(mu/epsilon)? Explain the term Young's modulus, bulk modulus and shear modulus of elasticity. ...

Here, K is the yield stress of the material in pure shear. Yield stress is the point at which the material behavior transforms from elastic to plastic. It is often said that the material yields if the stress is greater than the yield strength. The stress tensors are more generic in rea...
Metal fatigue is one of the subtlest types of metal failures, and one of the most dangerous. Although metal failure can occur from excessive tensile loads, shear loads and impact loads, to name a few, metal fatigue is a failure type that can go unnoticed right up until the point when ...
Von Mises is a measure of stress intensity for ductile materials such as steel. If the stress intensity calculated is 6.253e3 and the yield stress is 2e4 then stresses are within yield and the structure won't break. Fatigue damage should still be assessed though if your loads vary over time...
