Strength of materials print that page

In materials science , the strength of a material is its ability to withstand an applied stress without failure. The applied stress may be tensile , compressive , or shear . Strength of materials is a subject which deals with loads, deformations and the forces acting on the material. A

Strengthening mechanisms of materials print that page

Methods have been devised to modify the yield strength , ductility , and toughness of both crystalline and amorphous materials . These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a variety of different applications. For example

Segregation in materials print that page


important field of study of impurity segregation processes involves AES of grain boundaries of materials . This technique includes tensile fracturing of special specimens directly inside the UHV chamber of the Auger Electron Spectrometer was developed by Ilyin [13,14]. Segregation to grain

Stress–strain curve print that page

During tensile testing of a material sample, the stress– strain curve is a graphical representation of the relationship between stress , derived from measuring the load applied on the sample, and strain , derived from measuring the deformation of the sample, i.e. elongation, compression

Structural material print that page


Structural engineering depends on the knowledge of materials and their properties, in order to understand how different materials support and resist loads. Common structural materials are: Contents 1 Iron 1.1 Wrought iron 1.2 Cast iron 1.3 Steel 1.4 Stainless steel

Solid print that page


state physics , and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials , as well

Rheology print that page


Although this viscosity will change with temperature, it does not change with the flow rate or strain rate. Only a small group of fluids exhibit such constant viscosity, and they are known as Newtonian fluids. But for a large class of fluids, the viscosity change with the strain rate (or

Fracture mechanics print that page


In modern materials science , fracture mechanics is an important tool in improving the mechanical performance of materials and components. It applies the physics of stress and strain , in particular the theories of elasticity and plasticity , to the microscopic crystallographic defects
