描述
目前,全球有超过7500个招聘广告的关键词是“有限元分析”和“计算机辅助工程”。这些工作的薪酬正在飙升,需求也在以惊人的速度增长。

原因很简单。几乎所有的公司都意识到了仿真辅助设计过程的重要性。他们正在想办法将模拟纳入他们的产品开发生命周期,并且需要有技能的人来帮助他们这样做。

但问题是。

公司希望人们了解事物的全貌,并适应不断变化的产品设计环境。不是一个知道理论但发现很难在现实生活中应用的人。

本课程正是为了弥合有限元理论和应用之间的差距。

让我透露一个秘密。如果你不打算成为一名有限元工具开发人员,你不需要大学里教的所有数学知识,也不需要标准有限元教科书中详细描述的数学知识。相反,您需要对有限元分析的概念有一个清晰的概念理解,然后有能力从商业可用的有限元分析包中选择和使用正确的工具。

在本课程中,我将从实用的角度带您了解有限元分析的不同步骤。它将完全面向应用程序,我将介绍一些来自该行业的案例研究,让您了解行业专业人员如何将复杂的问题分解成小块,然后逐步解决它们。我还将谈谈有限元分析中许多常见的误解术语的物理意义。团队合作总是向前推进的,这些术语将帮助您与团队中的其他FE分析师和设计工程师有效沟通。

然后,我将介绍一个Python脚本框架,它可以用来用ABAQUS模拟问题。我将使用这个框架来帮助您为5个不同的问题编写Python脚本,并使用ABAQUS来解决它。

这就是这门课程如何为你增值的。

你还在等什么?现在就行动,让自己通过这门课程的认证。

这门课是给谁上的:
机械/土木工程专业的学生,希望以实用的方式理解有限元分析,而不会受到复杂数学的轰炸
希望在日常工作中立即应用有限元分析的行业初级有限元分析人员
设计工程师希望过渡到一个FE分析师的角色
希望在ABAQUS中使用Python脚本框架以提高生产率的工程师
希望在决策之前了解有限元分析更大图景的经理
想要确定有限元分析中使用的重要术语的基本原理的技术销售专业人员
缺少人力和时间,希望快速提高对有限元分析理解的中小型公司

Description
Right now, there are more than 7500+ job advertisements, globally, for keywords “Finite Element Analysis (FEA)” and “Computer Aided Engineering (CAE)”. The pay for these jobs are spiking up and the demand too is increasing at an insane rate.

The reason is simple. Almost all companies have realized the importance of simulation-assisted design processes. They are figuring out ways to incorporate simulation in their product development lifecycle and need skilled people who can help them do that.

But here’s the catch.

Companies want people who understand the bigger picture of things and adapt to the ever-changing landscape of product design. Not someone who knows the theory but finds it difficult to apply it in real life.

This course is exactly intended to bridge that gap between FEM theory and application.

Let me reveal a secret. If you are not going to be a FEM tool developer, you don’t need all the math that is being taught at the university or being described in detail in standard FEM textbooks. Rather, you need a clear and conceptual understanding of the concepts of FEA and then the aptitude to select and use the right tools from the commercially available FEA packages.

In this course, I will take you through different steps in Finite Element Analysis from a practical perspective. It is going to be fully application-oriented and I will present some case studies from the industry that will give you an idea of how industry professionals break down complicated problems into small chunks and then solve them gradually. I will also talk about the physical meaning of a lot of commonly misunderstood terms and terminologies in FEA. It’s always teamwork going ahead and these terminologies would help you to communicate effectively with other FE Analysts and design engineers in your team.

Then, I will introduce a framework for Python scripting that could be used for simulating problems with ABAQUS. I will use this framework to help you write Python scripts for 5 different problems and solve it using ABAQUS.

That’s how this course will add value to you.

What are you waiting for? Act now and get yourself certified with this course.

Who this course is for:
Mechanical / Civil Engineering students who want to understand FEA in a practical way without getting bombarded with complicated math
Beginner FE Analysts from the industry who want to apply FEA right away in their work routine
Design engineers looking to transition into a FE Analyst role
Engineers who want a framework for using Python Scripting in ABAQUS to increase productivity
Managers who want to understand the bigger picture of FEA before decision making
Technical sales professionals who want to be sure about the fundamentals of important terms used in FEA
Small or medium sized companies who are short on manpower and time and want to quickly ramp up their understanding of FEA
