What
is Fracture? This is the first of a set of blog posts on the subject of
fracture testing. Traditional information on fracture testing focusses
on techniques for assessing engineering materials using standard methods
and strict geometries. However, these may not be so useful for the
typical user of a Texture Analyser.The loosest definition of fracture is “a form of failure in which the material separates into two or more pieces due to an applied load”. Fracture strength is the stress at which a specimen fails or fractures. Fracture can be brittle, ductile or semi-ductile. This refers to the nature of deformation and will be covered in the next post.
