Overview

What is deactivation nonlinear analysis? Is an analysis in which some elements in the model are activated or deactivated depending on the building process phase  Typical examples include machining process/assembly processes or analyses involving failure/removal of material such as excavation (as in tunneling or slurry wall excavation), staged construction (as in unshored bridge erection), sequential assembly, weld deposition, annealing, model ablation, etc.

Students of this course will learn fundamentals of nonlinear analysis,  numerical analysis of nonlinear problems how to perform an activation/deactivation nonlinear analysis and how to obtain convergence in the solution of different structures using advanced Finite Element Method software such as CivilFEM powered by Marc.

Training material

  • Base text: Specially created for the training program.
  • Software: Students of this course will have access to the student version of the FEM software CivilFEM powered by Marc to perform the exercises proposed.
  • Forums: Where the students have the chance to interact and consult with each other and the tutors.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • Some basics in nonlinear analysis: The basics of Nonlinear Analysis.
  • Numerical Analysis of Nonlinear Problems: Nonlinear problems require incremental solution schemes and solved with iterations to ensure that equilibrium is satisfied at the end of each step and some numerical methods are explained concerning this concept.
  • Activation/Deactivation Nonlinearity: Activation/Deactivation nonlinearity of some elements in the model occurs because of the building process phase that modifies the structural system´s behavior.
  • Convergence Problems in a nonlinear problem mostly is not just about the convergence of the solution and it is an overall issue of model integrity and representation of reality and its achievement sometimes becomes a difficult objective. In these sections some important aspects that help in the procedure of obtaining the converged solution are stated using CivilFEM powered by Marc.

Certificate of Completion

You will obtain a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
