Over the past half century, beginning in late 1960s and early 1970s, the True Triaxial Test (TTT) device has been developed and refined for experimental investigation of the mechanical behavior of rocks and other geomaterials under multi-axial loading paths (Mogi1967; Kwasniewski et al.2012). ...
I used an arduino nano every, an Aocrie 28BYJ-48 and test module board (available on Amazon) and an 100mmx68mmx50mm project box (also from Amazon). Instead of using the reset switch on the NMano, I used a spst momentary switch connected to the RST and GND terminals on the Nano t...
inputs. Using calculated test parameters directly eliminates complex and lengthy pre-calculations to design test programs. This allows the user to concentrate on the material behavior rather than on the electronics and equipment operation. GCTS offers ...
diffraction (XRD) or SEM–EDS analysis, and the published values of Young’s modulus and Poisson's ratio for each mineral were used in the calculations. Under the assumption that clay is the sole source of anisotropy, all other components were assumed to be isotropic. Consequently, the stiffne...
Therefore, calculations are made for positive and negative parity separately (with positive signature only). Reasons for new version: Now, there are several ways to obtain the eigenvalues and the eigenfunctions. The eigenvalues can be obtained from the subroutine 'eigvals' or from the array '...
