An advanced continuum damage mechanics model for predicting the crack progress process based on the consideration of the influence of crack direction under quasi-static load
Yun, Kumchol; Wang, Zhenqing; Ronald, Sakaya; Pak, Yongchol (Elsevier: International Journal of Mechanical Sciences., 2017-09)In reality the wrong crack path can be generally obtained in the case of arbitrary crack propagation by traditional continuum damage mechanics (CDM). In this paper a novel advanced continuum damage mechanics (ACDM) method ... -
A computational methodology for simulating quasi-brittle fracture problems
Yun, Kumchol; Wang, Zhenqing; Chang, Mengzhou; Liu, Jingbiao; Kim, Tae-Jong; Son, Namjin; Ji, Kyongsu; Ronald, Sakaya (Elsevier: Computers & Structures, 2019-04-15)The paper focuses on an efficient and simple methodologies for simulating the three dimensional (3D) quasi-brittle fracture problems. Strain-softening is performed on the elements by a developed anisotropic continuum damage ...
