Analysis of banded microstructures in multiphase steels assisted by transformation-induced plasticity
The influence of the spatial distribution of the austenitic phase on the effective mechanical properties of a multiphase steel assisted by transformation-induced plasticity is analyzed using a numerical homogenization scheme. Representative three-dimensional volume elements with distinct microstructures are created applying a newly-developed algorithm based on the generation of a multilevel Vor...
متن کاملComputational modeling of crack propagation in real microstructures of steels and virtual testing of artificially designed materials
A computational approach to the optimization of service properties of two-phase materials (in this case, fracture resistance of tool steels) by varying their microstructure is developed. The main points of the optimization of steels are as follows: (1) numerical simulation of crack initiation and growth in real microstructures of materials with the use of the multiphase finite elements (MPFE) a...
متن کاملStretch-flangeability of strong multiphase steels
Stretch-flangeability measures the ability of a material to form into a complex shape. The parameter is often related to simple properties derived from tensile tests. An attempt is made here to discover the best way to exploit tensile test data to indicate flangeabilty. It is found that the ultimate tensile strength of steel is the single most important criterion that correlates with stretch-fl...
متن کاملMultiphase Turbulent Modeling using LES
The modeling of multiphase, turbulent flows and their dynamics has become increasingly important in many environmental, geophysical, and engineering applications. These areas require the use of models that can effectively represent both the multiphase and turbulent characteristics involved in the simulation. Due to the large increase in computational power required to both simulate multiphase a...
متن کاملstudy of hash functions based on chaotic maps
توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
