Keywords

Learning Prerequisites

Required courses

ME-232 (Structural Mechanics), ME-201 (Continuum Mechanics), and ME-331 (Solid Mechanics), or equivalent from other institutions.

Recommended courses

ME-202 (Mechanical Systems); ME-373 (Finite element modeling and simulation).  It will be beneficial for students to have taken ME-437 (Advanced Solid Mechanics), or to be taking it in parallel to this course, even if this is not required.

Important concepts to start the course

Familiarity with structural analysis of elastic systems (bars, trusses, beams, trusses, frames, and mechanisms) and boundary value problems in elasticity. The emphasis of the course is primarily on analytical methods to rationalize and model the mechanics of slender structure, hence, an affinity to mathematical and theoretical approaches in problem solving is expected.

 

Learning Outcomes

By the end of the course, the student must be able to:

• Model Model and analytically solve simple problems of statics and stress analysis, S1
• Solve Analyze and design assemblies of simple mechanical elements in the framework of static and buckling, S2
• Analyze Model with analytical or numerical tools the nonlinear response of structures and materials, S12
• Estimate
• Interpret
• Prove
• Choose
• Formulate

Transversal skills

• Use a work methodology appropriate to the task.
• Set objectives and design an action plan to reach those objectives.
• Plan and carry out activities in a way which makes optimal use of available time and other resources.
• Assess progress against the plan, and adapt the plan as appropriate.
• Continue to work through difficulties or initial failure to find optimal solutions.
• Assess one's own level of skill acquisition, and plan their on-going learning goals.
• Demonstrate the capacity for critical thinking

Teaching methods

Lectures, practical demonstrations, example problems, in-class exercises, and homework.

Assessment methods

The course concludes with a written exam (100% of the grade).
