STRUCTURAL DAMAGE DETECTION BY USING TOPOLOGY OPTIMIZATION FOR PLANE STRESS PROBLEMS

This paper aims to introduce topology optimization as a robust tool for damage detection in plane stress structures. Two objective functions based on natural frequencies and shape modes of the structure are defined to minimize discrepancy between dynamic specifications of the real damaged structure and the updating model. Damage area is assumed as a porous material where amount of porosity sign...

Solving Software Reuse Problems with Theorem Provers

For a challenging application, the software component retrieval , we present a powerful solution by combining two systems. The NORA/HAMMR-tool handles all aspects concerning with the logical representation of the application problem, the ILF-tool provides an infrastructure to apply several ATPs like SETHEO, OTTER, SPASS to the emerging deductive problems. For a fruitful practically application,...

An Extended Cutting Plane Method for Solving Convex Minlp Problems

An extended version of Kelley’s cutting plane method is introduced in the present paper. The extended method can be applied for the solution of convex MINLP (mixed-integer non-linear programming) problems, while Kelley’s cutting plane method was originally introduced for the solution of convex NLP (non-linear programming) problems only. The method is suitable for solving large convex MINLP prob...
