Among the various sources of waves, the explosion is an important factor. After explosion, considerable energy is released in a short time. This energy is emitted into the environment as seismic waves and vibrates the particles in the environment and after that, energy absorption in the environment eventually lead to the weakening of wave propagation and finally wave attenuation. Formulation problems in many branches of science, especially science engineering, leads to differential equations; therefore, faster and more accurately solve the equations of the important issues that underlie many forms of research. In this paper, at first, the analytical solution of two-dimensional wave equation with a source of shock and boundary value using the Green's function method is discussed and then the analysis of explosion process is done by using the Finite Difference Time-Domain Method. The analysis conducted in this paper examine the effect of distance and weight of the explosive.}, keywords = {Waves propagation,wave front,explosion,Green's function}, title_fa = {حل تحلیلی جبهه موج حاصل از انتشار امواج انفجار با استفاده از تابع گرین}, abstract_fa = {انتشار امواج یکی از مهمترین مسائل مطرح شده در صنایع نظامی، پدافند غیرعامل و ساخت وساز می باشد. از میان منابع مختلف تولید امواج، انفجار به عنوان یک عامل مهم حائز اهمیت است. در این مقاله، ابتدا به حل تحلیلی معادله موج دوبعدی با یک منبع ضربه ای و مقدار مرزی با استفاده از روش تابع گرین پرداخته شده و سپس تحلیل فرآیند انفجار با استفاده از روش های عددی و مدل سازی در نرم افزار متلب انجام شده است. تحلیل های انجام شده در این مقاله، تاثیر فاصله انفجار و میزان ماده منفجره را مورد بررسی قرار می دهد.}, keywords_fa = {انتشار امواج,جبهه موج,انفجار,تابع گرین}, url = {https://jmep.isme.ir/article_33772.html}, eprint = {https://jmep.isme.ir/article_33772_6551690e6d15e5b16eb2cdd2b86861b6.pdf} }
