Abstract
Empirical models were developed to relate stress with a resistance of materials that helps to predict the response of materials. For porous materials, measuring the pore parameters is required to incorporate the intensification effect of the pore on the stress distribution. However, image analysis is the common practice employed to measure pore parameters, mathematical models may also use as an alternative method. Mathematical modeling of pore parameters for square, triangular, and rectangular geometric pore was developed. Pore parameters used to characterize circularity (fcircle), elongation (fshape), and the pore size (equivalent diameters, Deq.) were analyzed for those geometric pores. The analytical results were compared with the pore parameters measured on the microstructures of prealloyed sintered steels. The modeling results are in agreement with the experimental analysis.
