From Oct 16th to 19th, ICADD-12 (12th Interntational Conference on Analysis of Discontinuous Deformation) was held in Hongshan Hotel, Wuhan. The conference is held once every two years, the famous universities and research institutes in Asia, Europe, America, Australia and other countries undertake this conference in turn. ICADD-12 is IRSM declared successfully in ICADD-11, which was held in Fukuoka, Japan, sponsored by ISRM DDA committee, CSRME commission for ground rock engineering, commission for rock dynamic mechanics, undertaken by SKLGME, Dalian University of Technology, China Renewable Energy Engineering Institute, Wuhan University, Changjiang River Scientific Research Institute, and ITASCA China. Tang Chunan, Jiao Yuyong are the chairmen of the committee, Dang Lincai, Liu Quansheng, Wu Aiqing, Zhao zhiye, Wang Ying are vice chairmen. On Oct 16th, ISRM DDA committee held 2015 annual meeting in IRSM, discussed the research progress in the field of discontinuous medium numerical method, and other important matters of ICADD next sponsors.
Researcher Jiao Yuyong hosted the opening ceremony on 17th, Professor Tang Chunan had the opening speech, the founder of DDA and NMM, Chinese-American scientist Professor Shi Genhua, former vice chairman of ISRM, vice chancellor of Kyoto University Professor Yuzo Ohnish, deputy director of IRSM researcher Sheng Qian, China Renewable Energy Engineering Institute Dr. Du Xiaokai, deputy director of SKLGME researcher Zheng Hong, Changjiang River Scientific Research Institute Professor Wu Aiqing, University of Western Australia Professor Ma Guowei, vice President of the institute of civil engineering, Wuhan University Professor Liu Quansheng, Nanyang Technological University Professor Zhao Zhiye were seated in rostrum. Six experts ( Shi Genhua, Yuzo Ohnish, Tang Chunan, Zheng Hong, Ma Guowei, Feng Xiating, respectively) gave the special reports.
