I.  Approach

            The objective of this course is to reinforce the concepts developed in the course MAE 131B (Solid Mechanics II) and to extend these concepts to tri-dimensional stress and strain.  The solution of plane stress or plane strain elasticity problems can be reached by use of the potential function, and important cases will be treated:

 

            *Stresses around circular and elliptical holes

            *Contact stresses

            *Stress distribution near a concentrated external load

 

The limits of elasticity in complex loading situations are determined by the yield criteria (if the material is ductile) and failure critical (if the material is brittle).  The principal criteria will be introduced and discussed. 

The indicial notation, in which a 3 x 3 matrix of stresses and stains is represented by  and  respectively, is discussed.

 

 

II.  Grading

            The grades will be based on exams, homework, and reports.  They will count as follows:

 

                                    First Exam                    25%

                                    Second Exam                25%

                                    Final Exam                    25%

                                    Homework                    25%

 

Homework will be assigned on Tuesdays and will be due the next Tuesday (at the beginning of the class).  NO LATE HOMEWORK WILL BE ACCEPTED.  The homework should be neat and written on yellow engineering paper.  The total value will be of 25 pct.  Grading will be done on a statistical basis from results obtained by the class.

 

            Thus, students are strongly encouraged to work diligently on their homework.  Make-up exams will only be given if the student presents a medical certificate.
