A 17-node quadrilateral spline finite element using the triangular area coordinates
《Applied Mathematics and Mechanics(English Edition)》2010年第1期125-134,共10页陈娟 李崇君 陈万吉 
supported by the Natural Science Foundation of China China (Nos. 60533060, 10672032, and 10726067);the Science Foundation of Dalian University of Technology (No. SFDUT07001)
Isopaxametric quadrilateral elements are widely used in the finite element method. However, they have a disadvantage of accuracy loss when elements are distorted. Spline functions have properties of simpleness and con...
