Prof. Huh Hoon of KAIST Computational Solid Mechanics and Design Lab. 
Taking value creation for human, Industries and future

Korea’s first ‘High Strain Rate Tester’ narrows down the gap of the world 
The term ‘science’ in our daily life can be rather obscure as most of us take it for granted. Subway or vehicle takes us where we wish to be in the morning during which we scroll up and down our smart phones and get off at the destination and turn on the computer or machine or whatever that needs to be powered for us to start a day. In all of these shifts and movements, there is science and engineering in it. Prof. Huh Hoon of KAIST Computational Solid Mechanics and Design Lab. is one of the most acclaimed authorities of world in the ‘Plasticity’ and the ‘impact simulation’. And ‘human-centered value creation engineering’ and ‘practical research toward human welfare’ always have been two core challenges that drove his passion. 
Prof. Huh and his team use ‘Computer Aided Simulation’ to analyze and assess the issues of the high reliable mechanics and design in the engineering system. The team draw fast results through computer simulations such as VR, VE and CAE, which are almost impossible in real tests requiring tremendous amounts of time and cost. The results from the computer simulations are turned into the useful data that can bring substantial application effect. For that purpose, Prof. Huh developed Korea’s first ‘High Strain Rate Tester’ that measures ‘high speed mechanical properties’ 20 years ago at the investment of around 200 million won ($200,000). And the KAIST Computational Solid Mechanics and Design Lab. became the only place in Korea that can produce ‘high speed mechanical properties data’. In recognition of this achievement, the KAIST Computational Solid Mechanics and Design Lab. was designated as the ‘High Speed Mechanical Properties Data Center’ of the National Center for Standard Reference Data by the Ministry of Trade, Industry and Energy in 2010. “It costs more than 800 million won to purchase a complete set of high strain rate tester from overseas and this is a considerable amount for a university to afford. Even if it was afforded, it would be invested to other equipment which draw immediate substantial results.” In fact, Prof. Huh developed the methodology to precisely calculate the uncertainty of measurement on the material properties at the intermediate and high strain rates and standardized the method for the first time in the world. The uncertainty measurement of the material properties enables engineers to predict the deviation of the material properties and thus to enhance the reliability of the computer simulation. This is one of the must-necessary methods for the development of industrial technologies, but industries and universities in Korea rather seem to underestimate and ignore, some say. 

Ceaseless efforts in bringing substantial results to industries
To improve the situation, the High Speed Mechanical Properties Data Center produces national reference standard data of the high speed material properties on vehicle, high speed transportation, electronic materials and structure materials. Currently, 290 cases of 50 kinds of certified standard reference data and 190 cases of 39 kinds of validated standard reference data for steel sheets, structural steels and nonferrous materials are uploaded for dissemination to industries, universities and research institutions as reference. The center also produced 340 cases of 64 kinds of high speed mechanical properties data for structural steels, polymer composite materials and aluminum alloys, all of which are open to industries and research institutes on the center’s homepage. “I think the role of professor is fostering talented manpower and doing researches that can bring substantial results to the industries. And the talents and the results naturally lead to the development of the industries’ capability and the enhancement of Korea’s superiority to other countries.” The contribution Prof. Huh has made, in relation to high speed material properties, are vast with around 180 materials and to name a few: car crash analysis; high speed metal forming; high speed mechanical properties on offshore construction, power turbines, electronics; energy absorbing device in high speed train with tension bolts, shear bolt, expansion tubes; nuclear waste container; and various kinds of warheads. Meanwhile, Prof. Huh served as the president of the Korean Society for Technology of Plasticity and the vice president of the Korean Society of Automotive Engineers. He also worked as the editor and the editor-in-chief of the International Journal of Automotive Technology for the last 13 years. The number of research papers published accounts to 230 and the number of papers presented at various conferences home and abroad is about 430. In 2013, one of Prof. Huh’s articles was ranked as the first for number of paid downloading in the International Journal of Solids and Structures, which is also called as ‘Top hottest Articles’. Prof. Huh names ‘education, research and service’ as the three core elements he always keeps in his mind as a professor, scholar and engineer. <Power Korea> sends a message of support.
