RISDeveloped Random Tessellation for Modeling of Microstructure
. The concept of random tessellation is extensively used in wide area of natural sciences, especially material sciences. In this paper a simple but complete explanation of the random tessellation and mathematical tools ...
Simulation of Random Microstructure and Study its effects on Scatter of Stress Intensity Range Factor Data
In this study, microstructure of Ti-6Al-4V is modelled by Voronoi random tessellation and by using sukumar algorithm; crack path of some areas of CT specimen at microstructure background is predicted. Development of sukumar ...
A Comparison of Macroscopic Fracture Surface and Crack Growth Rate of Ti-6Al-4V
A comparison between crack growth rate (da/dN) vs. effective stress intensity range factor (ΔKeff) curve behavior and microscopic and macroscopic fracture surface of commercial Ti-6Al-4V alloy are presented. Three different ...
موزاییک بندی تصادفی و کاربرد آن در مکانیک ریزساختارها
تقسیم بندی سطوح و حجم ها به قسمت های کوچک تر با شکل، اندازه و تعداد کاملاً تصادفی در اکثر علوم بویژه مهندسی کاربرد دارد. در این تحقیق ابتدا الگوریتم های ساخت نمودار ورونوی معرفی و برپایه این الگوریتم ها برنامه ای در نرم ...
Special criterion for crack path prediction at microstructure scale based on dominate slip system and grain boundary
This study develops a new method for fatigue crack growth analysis at microstructure scale. Proposed model was constructed based on material anisotropic and crystallographic planes. Firstly the material behaviour at ...
