Investigation of Structure-Property Relations in Porous Metals Using Finite Element Simulation
유한요소해석을 활용한 다공 금속의 구조-물성 관계 연구
Dongmyung Jung, Yongwoo Kwon
정동명, 권용우
Korean J. Met. Mater. 2019;57(11):747-754.   Published online 2019 Nov 5
DOI: https://doi.org/10.3365/KJMM.2019.57.11.747

Abstract
A porous material can be regarded as a mixture of pores and solid phases, with effective thermal and mechanical properties that significantly differ from those of its base material. Material effective properties depend greatly on the structure and porosity. The effective properties of materials with different pore structures can vary..... More

                        
A Study on the Variation in Tensile Ductility of Porous Sintered Iron
다공성 소결 순철에서 인장연성의 변화에 관한 연구
Jae-Young Jung, Ho-Sang Sohn
정재영, 손호상
Korean J. Met. Mater. 2018;56(1):34-39.   Published online 2018 Jan 1
DOI: https://doi.org/10.3365/KJMM.2018.56.1.34

Abstract
A model based on Irwin's approach to elastic-plastic deformation was applied to predict the tensile ductility of a sintered iron. The evaluation of this model using experimental results for porous sintered iron showed that tensile ductility depends not only on the pore volume fraction, but also the pore size and.....
