Stiffened plates are widely used in aerospace structures as load-bearing components. In order to obtain a novel design of stiffened with excellent performance, generative method (GDMSP) based on the homogenization is proposed this paper, which optimizes stiffener layout an equivalent model. Then, detailed model can then be obtained by extracting path from discrete distribution angles. Moreover,...

Several stiffened plates arrangements subjected to bending were configured applying the Constructal Design Method (CDM) and solved by Finite Element (FEM), aiming through Exhaustive Search (ES) technique analyze influence of transverse I-Shaped or T-Shaped stiffeners in mechanical behavior. Considering a non-stiffened plate as reference maintaining total steel volume constant, portion was deduc...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

The objective of current work is to show the effectiveness of using wavelet transform for detection and localization of small damages. The spatial data used here are the mode shapes and strain energy data of the damaged plate. Because the wavelet coefficients are performed with various scale indices, local perturbations in the mode shapes and strain energy data can be found in the finer scale t...

Stiffened plates are employed in various engineering structures including aerospace, civil, naval, etc. These may be subjected to harmonic loads. Therefore, it is essential understand the response of a cracked stiffened structure. This study presents effects crack location on free vibration and plates. For this purpose, horizontal vertical cracks modelled throughout fixed from two-side The anal...

The paper presents the application of a novel fast numerical tool, based on Generalised Beam Theory (GBT), to perform buckling and post-buckling analyses of laminated CFRP panels. GBT is a beam theory developed for prismatic thinwalled members (e.g., columns, beams or panels), which takes into account both global and local deformations. One of its main features is the fact that the cross-sectio...
