Progettazione agli Elementi Finiti
Finite Elements in Mechanical Design
Marco Rossi

Seat Ingegneria
A.A. 2015/2016
Credits 6
Hours 48
Period II
Language ENG

Prerequisites
for the comprehension of the subject covered in the course, the student need to have knowledge of the topics dealt with in the Machine Design and related preparatory courses

Learning outcomes
The aim of the course is to give an advanced training on finite element analysis, with its applications on mechanical engineering. The course is subdivided in two parts, a theoretical part, where the basics of the method are provided, and a practical part, with the objective of training on the use of commercial finite element codes.

Program
the couse is divided in a theoretical part, where the basic Finite Element theory is presented, and an practice part, where the student is trained on the use of commercial FE codes. Theoretical part. Matrix strucutral analysis, concept of shape or displacement function, deformation matrix, elasticity matrix, stiffness matrix. Assembly of the stucture stiffness matrix. Loads and constraints application. Element types: truss, beam, three and four node plane elements. Plane stress, plane strain, and axialsymmetric formulation. Isoparametric elements. 3D elements. Outline on non-linear solution preocedures: contact, geometric and material non-linearity. Eigenvalue analysis, dynamic problems and buckling. Evaluation of mesh quality. Practice part. Training on commercial FE codes (Ansys,Abaqus). Case studies and and practice exercises in the classroom.

Development of the examination
LEARNING EVALUATION METHODS
two tests will be used: - oral examination on the theoretical topics explained during the course - the discussion of a report where the student explain how to solve a complex engineering problem using the finite element method

LEARNING EVALUATION CRITERIA
the student will be evaluated according to his comprehension of the Finite Element Method and his ability of apply it to complex problem usign a commercial software.

LEARNING MEASUREMENT CRITERIA
The learning measurement will be done on the basis of the confidence and the understanding shonw by the student during the exam

FINAL MARK ALLOCATION CRITERIA
The final mark will be the average of the mark given to the report and the one given to the oral examination
