About APACM
The International Association for Computational Mechanics (IACM) was founded to promote advances in computational mechanics. For the purposes of the Association, the subject of computational mechanics was defined as the development and application of numerical methods and digital computers to the solution of problems posed by engineering and applied science with the objectives of understanding and harnessing the resources of nature. IACM was formally established and the General and Executive Councils were confirmed. The Constitution gives equal emphasis to the three geographical regions of Europe-Middle East-Africa, the Americas, and Asia-Australia. The European and American Regions established their Associations earlier. In order to be in line with them, the Asian Pacific Region founded in the end of 1999, APACM.
History
During the early years of IACM since its inception in 1980s, there were only 3 National associations in Asian Pacific Region: China, Japan and Australia. In 1999, at the initiative of S. Valliappan with the support and co-operation of W. X. Zhong and T. Kawai, the APACM was founded at the end of 1999. In line with IACM, it was decided to have two councils: Executive Council and General Council. The current members of the two councils are as follows.
Executive Council (elected)
Chuin-Shan David Chen, Secretary General (Taiwan), Fangsen Cui (Singapore), Yuantong Gu (Australia), Xu Guo (China), Xu Han (China), Yoon Young Kim (Korea), C. W. Lim (Hong Kong), Hiroshi Okada, President (Japan), Sang Joon Shin (Korea), Yoshitaka Wada (Japan)
General Council (nominated by the national and regional associations (affiliated associations))
Ahmad Kamal Ariffin (Malaysia), Shu-Wei Chang (Taiwan), Nguyen Xuan Hung (Vietnam), Daigoro Isobe (Japan), Worsak Kanok-Nukulchai (Thailand), Tarun Kant (India), Junji Kato (Japan), Nasser Khalili (Australia), Cheol Kim (Korea), Hyun-Gyu Kim (Korea), Qing Li (Australia), Tzu-Kang Lin (Taiwan), Jun Liu (Singapore), Zhanli Liu (China), Andrew YT Leung (Hong Kong), Sanjay Mittal (India), Kenjiro Terada (Japan), Judy P. Yang (Taiwan), Ng Teng Yong (Singapore), Weisheng Zhang (China)
In 1999 there were 3 national associations: Australia, China and Japan. At present (2025) there are 13 National and Regional Associations (Affiliated Associations): China, Japan (2), Korea (2), Australia, Singapore, Taiwan, Hong Kong, India, Malaysia, Thailand, Vietnam.
About APCOM
The purpose of APACM is to promote the activities related to computational mechanics in the Asian Pacific region and to represent the region's interests in the International Association. It was agreed that one of the ways by which the computational mechanics activities can be promoted in the region is to organize the Asian Pacific Congress on Computational Mechanics (APCOM) in different countries of the region at an interval of three years. The first APCOM Congress was held in Sydney, Australia in 2001. The second Congress was held in Beijing, China in 2004 in conjunction with 6th WCCM. The third was held in Kyoto, Japan in 2007. The fourth was held in Sydney, Australia in 2010 in conjunction with 9th WCCM. The fifth was held in Singapore in 2013. The sixth was held in Seoul, Korea in conjunction with 12th WCCM. The seventh was held in Taipei, Taiwan in 2019. The eighth was held in Yokohama, Japan in 2022 in conjunction with 15th WCCM. The ninth was held in Brisbane, Australia in 2025. The tenth will be held in Busan, Korea in 2028 in conjunction with 18th WCCM.
Members
The Constitution defines the organization structure of the APACM, i.e. the General Council (GC), the Executive Council (EC), the President and the Secretary General. All National and Regional Associations in Asia-Australia region are represented in GC. Members of GC are nominated by the affiliated associations, and are approved by the current EC. Presidents of the National and Regional Associations affiliated to APACM are co-opted members of GC during their term of duty. The EC consists of (a) EC members nominated from among GC members and elected by the current EC, and (b) the current President and the current Secretary General, and (c) the past Presidents and the past Secretary Generals before 2012. The President and the Secretary General are elected by EC from among the elected members of EC, and approved by GC.
