Comparison Of The Results

The newly developed spline finite strip method has been applied to determine the natural frequencies of plates and stiffened plates with edged elastically restrained against translation and rotation. The stiffener has been modelled so that it can be situated anywhere within the plate strip. The formulation has been generalized in such a manner that it can handle general shaped plates and stiffeners having arbitrary orientation and eccentricity. A consistent formulation has been adopted to incorporate the contribution of the edge restraints in the structural stiffness matrix. Numerical examples as available in the literature are solved and the comparison of the results indicates good accuracy of the method. New results in the form of natural frequencies corresponding to the higher modes particularly for plates/stiffened plates with nonclassical boundaries are presented.

Spline Finite Strip

Spline finite strip method is the basic theory to analyze the cold-bending formation. Based on principle of virtual work by spline finite strip method, energy model of strip element was established. The qualitative forming factors which are difficult to quantify, and the constraint conditions to form model were given into information description. Combing with specialist experience, solving task system of multi-Agent was established. By amending the Agent of knowledge containers and social relationships, every random factor influencing on forming quality effected objectively in the multi-Agent systems based on the changing environment. Then, the formation of dynamic task is solved. This work can provide theoretical guidance for complex design of steel in roll pass.
