#### Course Description

Welcome to this course of Aerospace Mechanics of Materials. We are happy that you chose to join us on this exciting journey. This course deals with basic material and geometry dependent analysis of structures. In this course, you will investigate how these material properties, in combination with structural geometries, affect the design and performance of basic structural elements under axial, torsion, bending and shear loading.

We have divided this course into eight different subjects and a review chapter. In those subject, you will find video lectures and readings, where the concepts and theory will be explained; examples, where we will solve a problem for you, so you can reinforce the concepts you have learned; and exercises, that will allow you to test your knowledge.

#### Learning Objectives

By the end of this course, we expect you to be able to…

Understand

• Explain the interrelation between force, displacement, internal stress and internal strain using the Generalized Hooke’s Law for Basic Load Carrying Members. In this course, Basic Loading Carrying Members refer collectively to axial load carrying members (bars, rods, cables, etc.), torsional shafts (circular and thin walled), and beams subjected to moment and transverse shear.

Apply

• Apply standard force/displacement relations and force/stress relations for Basic Load Carrying Members to solve for reaction forces, displacements, and stresses in statically determinate and indeterminate problems.
• Develop force/displacements relations for Basic Load Carrying Members that include varying geometry, material properties and/or loading.
• Apply Mohr’s Circle and failure criteria for complex stress states.

Analyze

• Breakdown complex structures into Basic Load Carrying Members with their associated loading conditions using the principle of superposition, equilibrium, and Free Body Diagrams.
• Formulate appropriate displacement relations to describe the deformation compatibility of statically indeterminate systems.
• Question the validity of magnitude and direction of calculated forces, displacements, and stress bases on their compatibility with loading geometry, and expected deformation.

Evaluate

• Assess the influence of changes in boundary conditions, structural geometry, material properties and loading deformation and stress state of a given problem.
