چکیده

Bu çalışma, deneysel ve sayısal olarak kompozit yamalar ile tamir edilen çatlaklı sandviç kirişlerin eğilme darbe davranışını araştırmaktadır. Sandviç kiriş elemanları yüzey tabakaları, cam elyaf takviyeli kompozit, köpük çekirdek, PVC malzeme yapıştırıcı tabakalardır. Üst tabakasına çatlak oluşturularak hasar verilmiştir yama yapıştırılarak edilmiştir. Düşük hızlı davranışı, farklı malzemeleri, kalınlıkları enerjileri açısından incelenmiştir. Sayısal analizleri, kirişin modellemek testi sonuçlarını karşılaştırmak için yapılmıştır. PYTHON program dili parametrik modelleneme Sonlu elemanlar alt programı ABAQUS-VUMAT kullanılarak 3B Hashin modelleri tabakalarına uygulanmıştır. Son olarak, hasarlı rijitliği uygulaması artırılmıştır. toleransları, temas kuvveti değişimleri, kinetik enerji varyasyonları sonrası modları dikkate alınarak parametreleri belirlenmiştir.

An Experimental Study on the Tensile Behavior of the Cracked Aluminum Plates Repaired with FML Composite Patches

Repairing of the cracks by fiber metal laminates (FMLs) was first done by some aeronautical laboratories in early 1970s. In this study, experimental investigations were done on the effect of repairing the center-cracked aluminum plates using the FML patches. The repairing processes were conducted to characterize the response of the repaired structures to tensile tests. The composite patches wer...

Generalized Warping In Flexural-Torsional Buckling Analysis of Composite Beams

The finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). The contacting materials, that constitute the composite cross section, may include a finite number of holes. A compressive axial load is applied to the beam. The...

Dynamic Response of Multi-cracked Beams Resting on Elastic Foundation

Cracks cause to change dynamic response of beams and make discontinuity in slope of the deflection of the beams. The dynamic analysis of the Euler-Bernoulli cracked beam on the elastic foundation subjected to the concentrated load is presented in this paper. The stiffness of the elastic foundation and elastic supports influence on vibrational characteristics of the cracked beam. The Dynamic Gre...

LQG vibration control of sandwich beams with transversely flexible core equipped with piezoelectric patches

The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...

Flexural-torsional stability of sandwich tapered I-beams with a functionally graded porous core

The present research deals with the flexural-torsional buckling analysis of sandwich web and/or flanges tapered doubly-symmetric I-beam. All section walls are composed of two metal face layers and a functionally graded (FG) porous core. It is assumed that the material properties of the porous core vary gradually in the longitudinal direction according to the simple power-law function considerin...
