Welcome to the Structural Engineering Abaqus Tutorial, the only course you need to learn how to deal with real-life structural engineering examples. This course is specially designed for mechanical, civil engineering students who want to expand their finite element knowledge. This course will teach you the theory behind input parameters as well as modelling and analyse the results.What you will get in this course:**This Course is divided into 12 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:An overview of this tutorial.Section 2:This section aims to teach you how to analyse various concrete beams under the 3-point bending condition. First, we start modelling the concrete beam only using CDP material property for concrete class B50, then in each video in this section, we try to reinforce the concrete beam with different methods such as steel bars and strips, CFRP and metal foam. There are two assignment videos in this section that will help you to test your newly learned skills.In addition, this section provides you with some background information about the concrete damaged plasticity (CDP), Hashin damage criterial for composite material and metal foam input parameters. It is highly recommended to watch all these videos and make sure that you understand the theory behind input parameters.Section 3:This section aims to teach you how to analyse various concrete columns under compressive loading. In this section, similar to the previous section, we start modelling concrete only then we reinforce the column using the combination of the CFRP laminate and Steel bars and strips.Section 4:This section consisted of two simulations, in the first simulations, we apply load to the concrete column without any reinforcement to have some damage (around 0.05%) on our column then the load will be removed, and CFRP layers will be used in the damaged area to increase the strength of the column and then the load will be applied again.Section 5:This section aims to teach you how to model the combination of the concrete beam and column under cyclic loading.Section 6:In this section, you will learn how to apply tensile loading to various engineering applications. This section consists of four examples: Concrete specimen, Aluminium specimen and single lap bolted joints under tensile loading and adaptive mesh. In addition, you will become familiar with ductile and shear damage theory in this section Section 7:In this section, you will learn how to apply impact loading on the concrete plate using the rigid and non-rigid projectile. In addition, you will learn how to import damage criteria for concrete using the.inp and keyword section by importing 32 required parameters. This section consists of three examples as follow: Concrete block under impact loading using rigid projectile (Example-1), Concrete block with two metal sheet reinforcement under impact loading using steel projectile (Example-2), Crushable foam under impact loading using rigid projectile (Example-3)Section 8:In this section, you will learn how to consider the thermal behaviour of the material under impact loading and how these properties could affect the results.Section 9:In this section, you will learn how to perform a low-velocity impact simulation with a fun example by simulating the phone drop from the height of 5 meters.Section 10:In this section, you will learn how to perform repetitive impact loading on the metal beam using the Johnson-cook damage model. Section 11:In this section, you will learn how to use the XFEM method to study the crack growth in a concrete beam under 3-point and 4 point bending conditions using 2D and 3D examples.Section 12:This section has some background information about all the damage models used in this course. 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.
