Why this course?
Aircraft Structures Stress Analysis and Certification can be a long, tedious and complex process if you don't know what you are doing. Mistakes can be expensive to the company. For all new and modified designs of these structures, the process begins with Aircraft Structures Modeling and extraction of interface loads for these complex structures. Then you proceed to perform detailed analysis checks and documenting the analysis in stress reports. But it does not have to be tedious, learn how to do it efficiently and have fun...
Once you learn the basics of the FEM Modeling process, both FEM and classical hand calculation methods are required to analyze these complex structures. These methods are typically not taught in traditional schools, you typically learn them on the job. Or, you can enroll in this aerostructures stress analysis course and learn yourself.
This course is ideal for stress or design engineers in the field of aerostructures.
Using both FEM and classical hand calculations, you will learn to analyze various components within these complex structures, step by step, using proven industry standard techniques I have personally used in my career.
The goal is to use what you learnt in the FEA course and the aircraft structures modeling course, extract loads, and then size various components, eventually generating stress reports documenting the analysis and margins of safety.
And best of all, you can enjoy any course, web page or blog post on this website, on any device such as a desktop, laptop, mobile or tablet. Make sure you have a wifi or a high speed internet connection with cookies enabled.
This course will lay the critical foundation you need for future advanced courses in aerospace stress analysis.
- Engineering college curriculum
- An interest in finite element analysis, aerostructures modeling and stress analysis methods
- Note that free FEMAP/NxNastran download and installation instructions are included in the FEA course
This course is divided into two main modules:
Module 1: Introduction Module
Int this module we will discuss the required skills to be a good "Stress Engineer", an intro to various cabin structures and components, and sizing methods.
Module 2: Analysis Module
In this main module, we will dig deep into the detailed FEA or classical hand calculation stress analysis methods depending on the component being analyzed such as sandwich panels or a floor fittings, among many other components.
Future: More Lessons
As time goes on, more lessons may be added to provide students with further knowledge on different kinds of structures to improve on the solid foundation already covered in the course.
In this video, we will dive into what the typical duties of a stress engineer are. We will also cover the educational background requirements. We will discuss the specific and expanded skill sets that characterize various experience levels for a good aerospace stress engineer.
Stress Analysis Module
Sandwich Panel Checks Part1
In this video, we will dive into the detailed sandwich panel checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will use and excel tool to practice MS calculations using the the FEM results.
Sandwich Panel Checks Part2
In this video, we will continue detailed sandwich panel checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will use and excel tool to practice MS calculations using the the FEM results.
Panel Pin Checks
In this video, we will dig into panel pin checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will use and excel tool to practice MS calculations using the the FEM results.
Potted Insert Checks
In this video, we will dig into potted insert checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will use and excel tool to practice MS calculations using the the FEM results.
Tie Rod Tube Stability Checks
In this video, we will dig into the axial tie rod tube stability checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will an excel tool to calculate the MS for the compressive failure mode of the tube.
Rod End Pin Checks
In this video, we will dig into tie rod end pin checks using FEM results from a "partition with cabinet" FEM from the Silver level course. We will use an excel tool to calculate the MS for the pin, the standard methodology found in the book "Bruhn", section D1.8 is used as described in the video.
Tie Rod Fitting Lug Checks Part2
In this video, we will continue with the tie rod fitting checks by classical hand calculations using the relevant sections in the book "Bruhn". This time we focus on sections away from the lug end.
Floor Fitting Section Checks
In this video, we will review how floor fittings are installed and cover section checks by classical hand calculation methods. We will also use a floor fitting FEM and results to go with the lesson.
Floor Fitting Base Pad Checks
In this video, we will analyze the bath tub type base pad of the floor fitting. Using the lessons so far, your assignments include base pad bolt hole bearing check and floor fitting bolt check.
Floor Fitting Design Improvements
In the previous video, you discovered some negative margin issues with the fitting design for the assumed loading. In this video, we will make some improvements to the design to better distribute the loads at the fasteners. It also includes some assignments for self study.
How long will it take to finish?
This answer depends on how much time you can dedicate. First it is mandatory you finish the two lower level courses before jumping into this course.
If you spend all day every day on both courses, you will finish them much faster than other students who may be working and have a few hours in a week to spend on the courses. So it varies from student to student.
