가상환경에서의 압력용기 균열평가시스템 개발을 위한 연구

초록

VR(Virtual Reality) technologies have been broadly used for the design, test, operation and diagnosis of industrial equipment. Recently many VR systems with walk through navigation and web databases; such as design and installation database, stress-time database, in-service inspection database et al. are developed. However, the VR system for evaluating cracked structure is not developed yet, because its procedure is too complicate to program by using the script languages; such as the Active Server Page, the Java Script and the Visual Basic Script which are commonly used to construct web environment. In this research, a web based stress intensity factor K calculation COM object called the ActiveK is developed with the Microsoft ActiveX technology. By using the ActiveK, one can easily calculate the K value of cracked structure based on the ASME B&P Code Sec. XI, API FFS RP579 and Raju-Newman method. Also, one can easily develop an application software for evaluating cracked structure in the web environment by linking the ActiveK and the VR model"
