Fracture mechanics gives a basic understanding of the characteristics of the structure afterload is being imposed on it.
To avoid failure of the structure, analysis of fracture mechanics is very important. Fracture mechanics is the study of causes of
cracks in a structure. A fracture means a crack of some length, the length of which increases upon loading. Fracture mechanics
is about when that crack becomes critical and cannot sustain the load imposed upon it. When the crack gets to sufficient long
length that the crack propagation goes from stable from unstable. For the structure to develop cracks, some energy is needed,
that energy is called fracture energy. Examination of the energy for understanding the limit of tensile stress a structure can
sustain is crucial. Usually for the development of crack three-point load method is used. A wide assortment has been proposed
for this technique, to be executed.
