that fall into the category known ashigh-cycle fatigue(HCF). The nominal stress method does not work well in thelow-cycle fatigue(LCF) region where the applied strains have a significant plastic component. In this region, a strain-based methodology must be used. 4.1 Defining Stress Cycles Fig...
Advanced numerical modeling for cold-formed light gauge steel structures, from manufacturing to the structural response under the applied loading, requires the knowledge of the stress-strain behavior of the material over the full range of tensile strains. Existing stress-strain models for carbon steels...

as illustrated in Figure 5.1 for a mild steel specimen taken up to failure. Several response regions are indicated there: linearly elastic(yield) strain hardening, localization and failure. These are discussed in the aforementioned course, and studied further in courses on Aerospace Materials.It is...
states that failure in any material occurs when the shear strain energy per unit volume stored in that material due to any loading exceeds the shear strain energy per unit volume stored in that material in the one-dimensional loading test (universal tensile test in the case of mild steel). ...

Examples of ductile materials are copper, mild steel, and thermoplastics. As should be realised from the materials just listed, ductility is not equated with weakness or compliance. Brittleness is a term used for materials that will fracture under stress without any applicable plastic deformation ...
The ductility of the adhesive layer in shear is the key property affecting the joint strength; the reference parameter is the ultimate adhesive shear strain energy, which is proportional to the toughness given by the area under the stress–strain curve (Hart-Smith, 1973a). In addition, ductilit...
