课程名称：爆炸模拟Abaqus教程 课程概述：欢迎加入爆炸模拟Abaqus教程，这是学习在不同应用中模拟各种爆炸条件的必修课程。本课程专为机械和土木工程学生及希望扩展有限元知识的工程师设计。课程将教授输入参数背后的理论，以及建模和分析结果的技巧。 课程结构：本课程分为四个部分，为了最大限度地受益，建议按顺序学习，因为基础术语仅在初始部分解释。 第一部分：气爆模拟 本部分教学如何使用CONWEP模型模拟固体和结构元素的气爆荷载，无需对流体介质建模。包含四个现实案例以及四个理论视频，介绍如何使用混凝土损伤塑性（CDP）和约翰逊-霍尔奎斯特模型对混凝土结构进行爆炸建模。此外，还将通过车门和复合梁的案例熟悉哈辛和约翰逊-库克损伤模型。 第二部分：平滑粒子流体动力学（SPH）爆炸方法 本部分将讲解如何应用平滑粒子流体动力学（SPH）这一数值方法，属于无网格方法的一种。这部分课程内容包括对混凝土梁和水箱的SPH爆炸方法的应用，以及鸟击对机身和喷气发动机的案例，以帮助理解该方法的其他用途。最后，通过子弹实例教授如何建模子弹壳中的火药爆炸。 第三部分：耦合欧拉-拉格朗日（CEL）方法 本部分教授如何将两种网格方法—拉格朗日与欧拉法—结合在同一分析中，从而避免高变形时的网格问题。这部分包含四个实例，前三个实例帮助在不同结构（如混凝土梁、地下管道和土壤）上模拟各种爆炸条件，第四个实例则通过模拟鸟击飞机机翼的情境展示该方法的其他用途。 第四部分：水下爆炸（UNDEX） 本部分将教授如何模拟水下爆炸。通过爆炸或声源产生的波动，分析如何影响结构表面。内容包括理解UNDEX荷载方法，及如何通过对潜艇和船舶结构模拟水下爆炸掌握延展性和剪切损伤模型的使用。 课程特别说明：本课程适合认真的学生，提供的实践知识和理论分析在网络上难以找到。课程使用Abaqus版本6.14.1，因此请确保使用该版本或更高版本的用户以打开资源部分的文件。课程示例并不针对特定情况，学生需要自行验证其分析准确性。所有版权均被保留，任何未经授权的广播、公共表演、复制或重新录制均构成版权侵犯。
Welcome to the Explosion Simulation Abaqus Tutorial, the only course you need to learn how to simulate various explosion condition on different applications. This course is specially designed for mechanical, civil engineering students or engineers who want to expand their finite element knowledge. This course will teach you the theory behind input parameters as well as modelling and analysing the results.What you will get in this course:**This Course is the divided into the 4 sections and in order to get the most advantage of it, we highly recommend you to follow the course in order as the basic terms have been only explained in the initial sections.Section 1: Air-blast This section aims to teach you how to use the CONWEP model for air-blast loading on solid and structural elements, without the need to model the fluid medium. Four real-life examples plus four theory videos have been used for this section to teach you how to model explosion on the concrete structure using concrete damaged plasticity (CDP) and Johnson-Holmquist model. Moreover, you can familiarize yourself with Hasin and Johnson-cook damage model in the explosion on the car door and the composite beam examples. **Please do not miss the section 1 as all material theories have been explained only here.Section 2: Smoothed particle hydrodynamics (SPH) explosion methodThis section aims to teach you how to use the Smoothed particle hydrodynamics (SPH). This numerical method is part of the larger family of meshless (or mesh-free) methods where we are using only a collection of points to represent a given body rather than the usual method. Here, you will make yourself familiarize with SPH explosion method on the concrete beam and water-tank. Moreover, two examples of bird-strike on the fuselage and jet engine can help you to understand the other usage of this useful method. Finally, the bullet examples will teach you how to model gunpowder explosion in the bullet shell. Section 3: Coupled Eulerian-Lagrangian (CEL) method This section aims to teach you how to combines two mesh approaches-Lagrangian and Eulerian-in the same analysis. The purpose of this technique is to avoid mesh problems when performing simulations that involve high/extreme deformations. This section contains four examples which the first three examples help you to simulate various explosion condition on different structures (Such as concrete beam, under-ground pipeline and only soil) and the fourth examples help you find the other usage of this method by simulating the bird strike on the aeroplane wing. Section 4: Underwater explosion (UNDEX)This section aims to teach you how to simulate the underwater explosion. Here, waves produced by an explosion or sound source propagate from the source, impinging on and passing over the structure, producing a temporally and spatially varying load on the structural surface. This section helps you to understand UNDEX charge method and also how to use ductile and shear damage model in Abaqus by simulating under water explosion on submarine and ship structure. I hope you all enjoy these tutorials. Please send me a message if you think anything can improve the quality of this course as I am updating the course regularly.Many thanksArmin **This course is only intended for Serious Students. A lot of efforts have been done to provide a practical understanding of the Software, theory and analysis which is not available anywhere on the internet. ** Abaqus version 6.14.1 is used for this course, therefore in order to open files in the recourses section, you should have this version or any later version. However, you can still use the older version to do this tutorial.** These course examples are not intended to apply to any particular situation.
