Many natural and man-made structures can be modeled as assemblages of interconnected structural elements loaded along their axis (bars), in torsion (shafts) and in bending (beams). In this course you will learn to use equations for static equilibrium, geometric compatibility and constitutive material response to analyze these structural assemblages.

This course also provides an introduction to behavior in which the shape of the structure is permanently changed by loading the material beyond its elastic limit (plasticity), and behavior in which the structural response changes over time (viscoelasticity).

This is the second course in a 3-part series. In this series you will learn how mechanical engineers can use analytical methods and “back of the envelope” calculations to predict structural behavior.  The three courses in the series are:

Part 1 – 2.01x: Elements of Structures. (Elastic response of Structural Elements: Bars, Shafts, Beams). Next session starts October 2017

Part 2 – 2.02.1x Mechanics of Deformable Structures: Part 1. (Assemblages of Elastic, Elastic-Plastic, and Viscoelastic Structural Elements).

 Part 3 – 2.02.2x Mechanics of Deformable Structures: Part 2. (Multi-axial Loading and Deformation. Energy Methods). Next session starts October 2018

These courses are based on the first subject in solid mechanics for MIT Mechanical Engineering students.  Join them and learn to rely on the notions of equilibrium, geometric compatibility, and constitutive material response to ensure that your structures will perform their specified mechanical function without failing.

课程大纲

• Use Free Body Diagrams to formulate equilibrium equations in structural assemblages
• Identify geometric constraints to formulate compatibility equations in structural assemblages
• Understand the formulation of thermo-elastic, elastic-perfectly-plastic and linear viscoelastic models for the material response
• Analyze and predict the mechanical behavior of statically determinate and statically indeterminate structures composed of bars, shafts and beams
