What is In situ tests in Brasilia porous clay : J. A. R. Ortigao, R. P. Cunha & L. S. Alves, Canadian Geotechnical Journal, 33(1), 1996, pp 189–198 about?

The strain softening of a granular soil under a or' # ai # cr3' condition and along a wide spectrum of paths was investigated experimentally. Strain softening was found to be pathdependent. It can take the form of shear band formation, or it can occur without the development of any non-homogeneity. Shear band formation is not necessarily a consequence of boundary imperfections, but can occur as the inevitable response of a sample to certain stress states and shear paths. The conditions for shear band formation were established and three types of strain softening identified.
