Abstract

In this paper, the effect of the geometrical shapes of the mesh on the progress of pressure wave and magnitude was investigated in the dynamic simulations by using LS-DYNA finite element solver. Cubic, cylindrical and spherical geometrical shapes were chosen to be examined. ALE() method was carried out to model dynamic simulation. Peak pressure values at a target point were compared with the value obtained from the dynamic test in the test area. In conclusion, it was investigated that which mesh geometric shape could give more accurate results under the conditions specified in the study.

Özet

Bu makalede, LS-DYNA sonlu elemanlar çözücüsü kullanılarak gerçekleştirilen dinamik simülasyonlarda, bölüntünün geometrik şeklinin, basıncın havadaki ilerleyişine ve büyüklüğüne etkisi incelenmiştir. İncelenen geometrik şekiller kübik, silindirik ve küresel olarak seçilmiştir. Dinamik simülasyonu modellemek için ALE metodu kullanılmıştır. Hedef bir noktadaki pik basınç değerleri, test sahasındaki dinamik testten elde edilen değer ile kıyaslanmıştır. Son olarak çalışmada belirtilen koşullarda hangi bölüntünün geometrik şeklinin daha doğru sonuçlar verebileceği değerlendirilmiştir.
