Research Abstract

It is important for Engineering to determine stress intensity factor by using strain gages experimentally. The stress intensity factor is the parameter of a fracture mechanics.
This research developes the strain gage method for determining the stress intensity factor of crack.
The method to be developes in this researches consist of three methods as follows.
1. The first is the method to determine the opening-mode stress intensity factor K_1 with using extremely small sized strain gage consisting of 5 measuring grids.
2. The second is the method to determine the sharing-mode stress intensity factor K_<II>. This resrearch is made experimets of two types as follow.
(1) The tensile shear tests are carried with using compact shear specimens.
(2) The torsional tests are carried with using cylindrical shell with a crack.
3. The third is the separable method of mode II stress intensity factor in a mixed mode by using 0/90 deg. ring core rosette strain gages.
