Sonlu Elemanlar Yöntemi Kullanılarak Temporal Kemiğin Zayıf Noktalarının Statik Analizi ve Klinik Uygulaması

İnsan vücudu karmaşık bir yapıya sahiptir. Bu nedenle bu yapıyı incelemek için ileri düzeyde mühendislik araçlarına gereksinim vardır. Bu çalışmada, 5000 Pa basınçta altı farklı kişiden elde edilen temporal kemikler incelenmiştir. Bu basınç altında kemikler üzerinde meydana gelen gerilmeler, ANSYS Workbench yazılımı ile sonlu elemanlar yöntemi kullanılarak belirlenmiştir. Toplam deformasyonlar genellikle kemiklerin skuamoz bölgelerinde görülmüştür. Bu durum, temporal travmaların klinik açıdan değerlendirilmesinde önemlidir.

Static Analysis of the Most Weakness Part of Temporale Bone Using Finite Element Method and Its Clinical Importance

Human body have a complex structure. So, examine this structure require advanced level of engineering tools. In this study, temporale bones obtained from six different person were examined under the pressure of 5000 Pa. Stresses occurred on these bones under the applied pressure were determined using ANSYS Workbench finite element software. Total deformations were seen always on squamous part of the bones. This situation can be important for the clinical relevance of temporal trauma.
