IMMEDIATE-BUCKLING MODEL, HYSTERETIC MODEL, TEXTILE SIMULATION MODEL BASED ON THE SAME, AND COMPUTER-READABLE RECORDING MEDIUM STORING PROGRAM EXECUTING THE SAME

摘要

PURPOSE: An immediate-buckling model, a hysteretic model, a textile simulation model based on the same, and a computer-readable recording medium storing a program executing the same are provided to realistically simulate a wrinkling appearance and the hysteresis of the textile without using micro-meshing and a time-step by using the model not having the buckling instability. CONSTITUTION: The simulation uses the immediate-buckling model immediately occurring the buckling, not compressed, if a compressive forces is applied to both ends of a transformation unit approximating the textile. A tool for modeling a hysteretic characteristic between a curvature and the moment representing a buckling form includes the 'n' slip units(1-3) and the 'n' springs(K1-K4). The slip units form the 'n' pairs of a spring-slip unit by respectively connecting to the spring in parallel. The 'n' pairs of the spring-slip unit are connected to one spring(K0) in serial.
