... calibration is made, enforcing the ability of the proposed approach to predict the SRMs internal flow-field conditions. The numerical simulations show that NAWC n. 6 internal ballistics is completely led by the erosive burning, that is the root cause of the pressure peak occurring immediately after the SRM...

... subsequently calibrated by finite element calculations. The results show that the ratio of scratch force to normal force (or apparent friction coefficient) can be partitioned into two additive components: one due to interfacial friction and another associated with plastic deformation. The plastic component...

... deformation calibration stress analysis The confining pressure triaxial calibration test has traditionally served as the fundamental material characterization experiment in geomechanics. The procedure centers on applying hydrostatic pressure on a circular cylindrical specimen, followed by increasing...
