; accepted 28 April 2014 Abstract: The experiments and numerical simulation were conducted for ZL205A aluminum alloy cylindrical shell casting. The formation mechanism of the linear segregation produced...: cylindrical shell casting; linear segregation; formation mechanism; criterion; control method 1 Introduction As one of the high strength cast Al-Cu alloys [1], ZL205A, has been widely used......
from Love’s shell theory with beam functions as axial modal function. A manifold layered cylindrical shell configuration is formed by three layers of isotropic material where the inner and outer layers are stainless steel and the middle layer is aluminum. The homogeneous cylindrical shell is made-up of isotropic one layer with stainless steel. The governing equations with uniform external lateral......
and the dynamic interaction between the lining and surrounding soil was considered. The lining structure and the soil were treated as a cylindrical elastic shell and an infinite elastic compressible...Dynamic response of cylindrical lined cavity in elastic mediumGAO Meng(高盟)1, 2, WANG Ying(王滢)2, GAO Guang-yun(高广运)2(1.
