Abstract

Laplace dönüşümü kompozit ya da fonksiyonel derecelendirilmiş malzemelerin dinamik analizlerinde, zamana olan bağımlılığı ortadan kaldırmak için önemli bir yöntemdir. Zamandan bağımsız sınır değer problemleri analitik ya da sayısal olarak çözülebilir. Elde edilen sonuçlar fiziksel uzaya ters Laplace dönüşümü ile çevirilir. Bu yüzden seçilecek olan ters dönüşüm yöntemi tüm analiz adımlarında yüksek doğruluk elde edilmesi bakımından oldukça önemli olabilir. Bu çalışmada, Zhao Method I, Zhao Method II, Durbin Method ve Düzeltilmiş Durbin Methodları dinamik yükleme koşulları için uygulanmıştır. Analiz sonuçları, uzun süreli çözümlemelerde bile Düzeltilmiş Durbin ve Zhao Methodları ile güvenli ve stabil sonuçlar elde edildiğini göstermiştir. Fakat, Zhao Methodları ile kıyaslandığında Düzeltilmiş Durbin Methodu’nun programlama ve hesaplama yükü çok daha azdır.

Abstract

The Laplace transform is essential to satisfy the independence of time for the analysis of the transient response of the composite or functionally-graded materials. The time independent boundary value problem may be solved then either by numerically or analytically. The solutions should be inverted to the physical plane using inverse Laplace transform. Therefore, the selected numerical inversion method may be crucial to obtain the high accuracy throughout the whole analysis steps. In the present study, Zhao’s Method I, Zhao’s Method II, Durbin’s Method and Modified Durbin’s Method are applied to dynamic loading conditions. The analysis results show that the accurate and stable solutions even for long time inversion have been obtained by Modified Durbin’s Method and Zhao’s Methods. However, compared with the methods of Zhao’s, the computational and programing load of Durbin’s Methods are minimum.
