The fracture analyses using RBSM (Rigid Bodies–Spring Model) were carried out for coke models with simple pore in order to examine effect of defects on fracture behavior in metallurgical coke. The discussion about the analytical results summarizes as follows:
1) Plastic load of coke is affected by pore shape and directions of force around pores. As a result, it is clear that plastic load of coke is concerned with coefficient of stress concentration.
2) Stress varies with a decrease in pore wall thickness and these interferences affect fracture load of coke. Thus, it is shown that pore and thickness are important factors in coke breakage.
3) The result of discussion of number density of pore and porosity shows that porosity is the most important factor in coke fracture. In addition, it is shown that diameter of pore and thickness are not as important as porosity in coke fracture.
