In the case of 16 boundaries , cubic b - spline function taken as trial function , the solutions to nonlinear stability of truncated conical shells and spherical shells with variable thickness were obtained by the method of point collocation 在16種邊界條件下,以三次b樣條函數(shù)為試函數(shù),用配點法計算變厚度開頂圓錐殼和球殼的非線性穩(wěn)定。
Under action of uniformly distributed load , line load along inside edge or uniform moments along outside edge , upper and lower critical loads of truncated conical shells and spherical shells with linearly variable thickness were computed 出了在均布荷載、內(nèi)邊緣均布線荷載或外邊緣均布力矩作用下,線性變厚度開頂圓錐殼、球殼的上、下臨界荷載。
