Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid ... more

In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of ... more

Time-domain reflectometry or TDR is a measurement technique used to determine the characteristics of electrical lines by ... more

The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not ... more
