本文以3D電腦視覺量測I型破裂試件的應力強度因子KI，所採用的破裂試件為鋁合金6061-T6材料製成的CT (Compact tension)試件。本文於試件表面沿著與裂紋方向成60度的徑向線上，黏貼一組格點陣列，接著以3D電腦視覺系統，分別擷取CT試件變形前後之影像，以便利用插補橢圓法決定平面主應變的大小與方向，以求取應力強度因子。 A 3D computer vision was used to measure the stress intensity factor KI of a mode I fracture specimen. The fracture specimen used in this study was a compact tension (CT) specimen made of 6061-T6 aluminum. A grid of dots was positioned on the specimen sur
