The in-plane strength properties of a composite material, axial and transverse tension and compression and in-plane shear, are usually the first to be considered in design. However, ...

Although engineering materials are normally used in their elastic range it is necessary to expose them to higher stresses if they are to be shaped into components. It is also necessary to know the ...

During manufacture and assembly of products, there is a wide range of testing and inspection carried out to ensure the materials and items satisfy their specifications or are fit for the required ...

A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...

When graphene is subject to strain equal in all directions, it morphs into a new structure which is mechanically unstable. Using quantum theory and supercomputers, Chris Marianetti, Assistant ...
