Çatlaklı ankastre sandviç kirişlerin serbest titreşim analizi

Bu çalışmada bir ucu ankastre diğer ucu serbest olan kompozit sandviç kirişlerin serbest titreşimi incelenmiştir. Çatlaklı ve çatlaksız halde sandviç kirişin doğal frekanslarının doğrulanması analitik ve ANSYS yazılım programı ile sağlandıktan sonra daha hızlı çözüm elde etmek adına analizler ANSYS programı ile gerçekleştirilmiştir. Çalışmada U ve V çatlak yapısının doğal frekans değerleri üzerindeki etkisi farklı çatlak konumlarında, farklı çatlak derinliklerinde ve farklı çatlak genişlikleri için incelenmiştir. Çalışmada 3 ve 5 tabakalı sandviç kirişler incelenmiştir. İncelenen bu parametrelerin kirişin doğal frekans değerlerini önemli ölçüde etkilediği gözlemlenmiştir.

Free vibration analysis of cracked cantilever sandwich beams

In this study, the free vibration of composite sandwich beams, one end of which is fixed and the other end is free, was investigated. The verification of the natural frequencies of the sandwich beam with and without cracks was provided with analytical and ANSYS software. The analyses were carried out with the ANSYS program in order to obtain a faster solution. In the study, the effect of U and V crack structures on natural frequency values was investigated for different crack locations, crack depths, and different crack widths. In the study, 3-layer and 5-layer sandwich beams were examined. It has been observed that these investigated parameters significantly affect the natural frequency values of the beam.
