Course Aim

At the end of the course student will have ability

  • to formulate material models and perform numerical parametric analysis (FEM) of composites properties
  • to plan and perform mechanical testing of composites and analyze mechanical properties
  • to formulate boundary value problems for simple structures, analyze stress concentrations and failure sequence in composite structures
  • to design and optimize composite structures combining numerical simulations with experiments.
  • to apply homogenization techniques and analysis on multiple length scales
  • to work in a team with a role as a team member and as a leader
  • to analyze results and to present the orally and in a form of technical report

Contents

The course starts with application of numerical and sophisticated analytical methods to analyze mechanical performance of hierarchical composite materials on multiple length scales. A significant part of the course is aimed to structures made of composite materials and subjected to thermo-mechanical loads. This part includes: use of commercial software LAP for laminate analysis; analysis of equilibrium equations and boundary conditions for shells and laminated plates; methods of analytical solutions for simplest cases; application of FEM (ANSYS); analysis of damage initiation, development and final failure; mechanical testing of composite materials and structures (methods, design and analysis); FEM simulations of tests and structural performance etc. Design principles with composites in aerospace, car and wind energy applications. Project on own design of load bearing composite structure including simulations, manufacturing and experimental verification.


Realization

The course consists of lectures and a project work in groups of 3-4 students. Project includes design and numerical (FEM) simulations, manufacturing of composite structure and experimental verification. The results of the project work are presented in a written report and orally. Theoretical skills will be improved by individual work with support from the lectures and will be examined in a written exam.


Examination
The examination will consist of oral exam and evaluation of the written and orally presented project report. Both these examination parts will be graded.

 


Remarks
Good knowledge in English.

Examiner
Andrejs Pupurs - Associate Professor

Literature. Valid from Autumn 2012 Sp 1 (May change until 10 weeks before course start)
The course literature consists of book chapters and research papers distributed during lectures. Own literature search is part of the project work.
