English to Russian Tech/Engineering Engineering (general) Geomechanics

Подскажите, пожалуйста, устоявшийся перевод термина frictional-collisional, который встречается в следующем контексте:
Dry granular flows down an inclined channel: Experimental investigations on the frictional-collisional regime;
Frictional-collisional regime for granular suspension flows down an inclined channel;
Frictional-collisional equations of motion for granular materials and their application to flow in aerated chutes;
A frictional-collisional rheological model that treats the rapid and quasi-static flow contributions additively has been used to analyze plane shear flow.
Заранее спасибо
