Class Objectives
/Class Outline Computational mechanics is a field of academic area to study a response of mechanical system modelized mathematically and implemented into a computer by computational simulation. Recently, this field is indispensable for design and mechanical analysis of solid materials and structures. In this class, learn fundamental theories and computational method of the matrix method of strucutres and finite element method.

Class Schedule lesson1 What is the computational method ? Its purpose and applications
lesson2 Matrices, vectors and tensors
lesson3 Matrices, vectors and tensors (Continued)
lesson4 Fundamentals of continuum mechanics (Stress and strain)
lesson5 Fundamentals of continuum mechanics (Constitutive equation and boundary value problem)
lesson6 Variational method and principle of virtual work
lesson7 Analysis method of spring model in one dimension connected to matrix method of truss structure
lesson8 Finite element, descritization and finite element formulation
lesson9 Finite element, descritization and finite element formulation (Continued)
lesson10 Tutorial class #1 by a use of computer (Explanation of computational code in Fortran for two dimensional truss structure and analysis of example problems)
lesson11 Tutorial class #2 by a use of computer (Explanation of computational code in Fortran for two dimensional truss structure and analysis of example problems)
lesson12 Tutorial class #3 by a use of computer (Explanation of finite element code in Fortran for a two dimensional solid and analysis of example problems)
lesson13 Tutorial class #4 by a use of computer (Finite element analysis of two dimensional beams subjected to bending moment)
lesson14 Tutorial class #5 by a use of computer (Finite element analysis of two dimensional plates and rounded bars subjected to tension and shear)
lesson15 Tutorial class #6 by a use of computer (Finite element analysis of two dimensional plates with a hole subjected to tension)

Short examinations and final examination

[Homework]
It is possible to provide homeworks sometimes. Students do homework on their own and submission of homeworks is required in the beginning of next class.
In tutorial classes, homeworks by a use of computer are provided. Students can submit all the result through e-mail.

Text/Reference
Books,etc. Any textbooks are not used in this class. In stead of that, the printed matters are distributed.

PC or AV used in
Class,etc. 　

(More Details) Printed matters, Slides projected by a laptop computer

Learning techniques to be incorporated 　

Suggestions on
Preparation and
Review 1) Reviewing statics learned in the first grade.
2) Reading textbook and solving example problems to prepare for classes
3) Reviewing topics learned in the each class
4) Provided problems in the end of each chapter on the textbook are solved on their own.

Requirements

Grading Method Mainly, a total evaluation includes scores of the final examination, short examinations and homeworks. 70 % of the evaluation is done by the final examination and 30 % of that is the others. Students who take a grade over 60% of the evaluation can pass. If students who are absent more than four times of classes, they would loose a right to take a final examination.

Summary of Practical Experience and Class Contents based on it

Message A use of gfortran and editor installed on your own laptop is required. The software has already installed when the registered students are desired to take the opening course entitled "Computer programming". One of instructors of the course, Prof. Johzaki has already opened the website specially how to install and use the software. You can go to the following URL
https://home.hiroshima-u.ac.jp/tjohzaki/rgdl_html/programming/programming2020.html
Additionally, the another software "ParaView" is employed to visualize the results. The software can be download from

Please fill in the class improvement questionnaire which is carried out on all classes.
Instructors will reflect on your feedback and utilize the information for improving their teaching.
