Experimental Verification of Spline Stress Analysis Method for a Structural Composite Laminate Containing a Hole

A stress analysis method has been developed for a biaxially loaded fastener hole in a laminated plate of finite geometry. The method is based on a variational formulation involving complex variables. In this method, the equilibrium and compatibility equations are satisfied in the domain of the plate due to the employment of the complex stress potentials and all the boundary conditions are satisfied through a variational statement. Therefore, the requirement for finite width corrections in relatively large fastener hole cases is avoided. The method has been verified through comparison with finite element results.

The paper presents a method for the determination of the critical minimum scantlings for small high-speed vessels. Particular attention is given to the shell plating strength for hydrodynamic impact loads. The suggested method uses an integrated approach involving assumed loads, suggested safety factors, and preferred stress-analysis method. The stress analysis uses plastic theory based partly on the works of J. Clarkson and Thein Wah. Included in the paper is a comparison of the relative structural strength of several commercial, military, and experimental hydrofoil vessels along with a few planing boats and a seaplane hull. This shows the variation of existing vessel structures and compares them to the results obtained by the suggested method. Most commercial, military, and recreational vessels exceed the minimum scantlings of the suggested method. The most significant deviation is the hull of the seaplane:
