This theory box is concerned with K 1C testing and will give only a brief synopsis of the conditions to be met to obtain a valid plane strain fracture toughness value. During the fracture toughness test, load is applied within a set rate, corresponding to K changing in the range 0.

This enables proprietary data analysis in third-party spreadsheet software, for example.
