Abstract

Patlama ve patlamanın diğer cisimler üzerinde oluşturduğu etkilerin analiz edilebilmesi amacıyla birçok yazılım kullanılmaktadır. Bu yazılımların başında da ANSYS Autodyn yazılımı gelmektedir. Bu çalışmada, Suriye'nin Han Şeyhun şehrinde 4 Nisan 2017 tarihinde gerçekleşen gerçek bir kimyasal silah saldırı olayı, Sonlu elemanlar yöntemi kullanılarak ANSYS Autodyn yazılımı ile simüle edilmiştir. Yazılım, bombalama olayından sonra oluşan, sınır koşulları (mühimmatın türü ve özellikleri, zeminin özellikleri, mühimmatın hızı ve düşme yüksekliği) ve verileri bilinen kraterin, bu çarpışma ve patlama sonucunda oluşup oluşmayacağını analiz edebilmek için kullanılmıştır. Çalışmanın bulgularına baktığımızda, yapılan 6 farklı simülasyonun sonunda, özellikle de altıncı simülasyon sonucunda krater çapının %97 oranında krater derinliğinin ise %92,4 oranında gerçek değerlere yakınsadığı görülmektedir. Bu da söz konusu mühimmatın bu olayda kullanıldığı varsayımını güçlendirmektedir.

Finite Element Analysis Of a Real Man-made Disaster

Abstract

Many software is used to analyse the effects of an explosion and its impact on other objects. ANSYS Autodyn is one such software. In this study, a real chemical weapons attack event that took place in Khan Sheikhoun, Syria on 4 April 2017 was simulated using ANSYS Autodyn software using the finite element method. The software was used to analyse whether the crater formed after the bombing event, whose boundary conditions (type and properties of the munition, properties of the ground, velocity of the munition and height of fall) and data are known, will be formed as a result of this collision and explosion. Looking at the results of the study, it can be seen that at the end of 6 different simulations, and especially as a result of the sixth simulation, the crater diameter converged to the real values by 97% and the crater depth by 92.4%. This strengthens the assumption that the ammunition in question was used in this incident.
