Different aspects of the mechanical strength of brex (extruded briquettes) are studied. A finite-element modeling is performed of the fracture of long brex as they leave the die. A model is also constructed to describe the position of brex of oval cross section in a pile, the model making it possible to determine the distribution of the orientations of brex in the pile. Strength tests of brex specimens...
Physical modeling and a numerical simulation are performed to study the effect of the form of the cross section of an extruded briquette (brex) on its mechanical strength. It is shown that brex of oval cross section subjected to pressure from a load applied along the minor axis (with a semi-axis ratio of 1:2) are almost twice as strong as brex having a circular cross section. The study demonstrates...
