Skin-Stiffener Separation In Buckled Composite Plates And Shallow Shells, Mark Edward Robeson
Skin-Stiffener Separation In Buckled Composite Plates And Shallow Shells, Mark Edward Robeson
Mechanical & Aerospace Engineering Theses & Dissertations
The development of an approximate analysis for predicting stresses in the skin-stiffener interface region of composite plates and shallow shells is presented. The analysis determines interlaminar normal stress and transverse shear stresses in the direction of the stiffener axial coordinate and the direction of the inplane coordinate perpendicular to the stiffener axis. The analysis accounts for skin-stiffener interfaces with nonzero thickness and for curvature in the skin and stiffener. The interlaminar normal stress and transverse shear stresses at the interface are applied to the lower face of the skin and the upper face of the stiffener flange as unknown functions, …
