Excerpt

Numerical analyses in geotechnical engineering requires the development of constitutive equations and the assessment of parameters for material characterization. Essential for doing this is laboratory testing. One of the most frequently used and advanced geotechnical laboratory equipment is the so-called “triaxial” apparatus, which allows to apply an axi-symmetric state of stress to the soil/rock specimen (ISRM 1983). …
