アイソジオメトリック解析（IGA）を用いた疲労き裂進展解析システムに関する研究

抄録

A crack propagation analysis system has being developed by combining Isogeometric Analysis (IGA), which features high compatibility with CAD, precise geometric representation, and high-order continuity, with the singular patch method capable of representing stress singularities through geometric mapping. In particular, a method for generating the crack front curve after crack propagation and redefining IGA patches was proposed. The validity of the method was demonstrated through a surface crack propagation problems.
