Compared to metals such as aluminum and steel, the number of stiffness and strength properties associated with polymer matrix composites (PMCs) is extensive. For metals, these mechanical properties ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

This is a particular problem for smaller aircraft manufacturers who have neither the budget to develop the required databases, nor access to those generated by larger organizations, often in support ...

Under specific conditions, hydrogen can diffuse in metal, leaving a long-term effect on the material’s properties. Close investigation of the behavior of materials and components in hydrogen-rich ...
