Course description and aims
This course focuses on the fundamental concept of tensor and tensor analysis used in the analysis of continua. Topics include the usefulness of tensor analysis, the definition of base vectors, metric tensors, various definitions for strain tensors and stress tensors, constitutive equations, and numerical method applied to actual structural problems.
Curved continua like arches and domes are often applied to actual building structures for indoor sport stadiums. The specific coordinate system which was the most suitable one to the configuration of the target structure was referred to when deriving basic equations for the structure. Consequently, varied expressions of the basic equations were used corresponding to the problem. According to the concept of tensor analysis, the basic equations can be derived in the common form which is independent of the reference coordinate system. Students will realize both the usefulness and complication of tensor analysis. Conversely, students will know we have received the benefit from the Cartesian coordinate system in deriving various equations.
Student learning outcomes
By the end of this course, students will be able to:
1) Understand concept of tensor variables and difference from scalor or vector variables.
2) Understand the reason why the tensor analysis is used and explain usefulness of the tensor analysis.
3) Derive base vectors, metric tensors and strain tensors in an arbitrary coordinate system.
4) Explain concept of plasticity theory for multi-axial stress field.
5) Explain the geometrical nonlinearity which should be considered in designing arches or domes.
Keywords
Tensor, Tensor analysis, Base vector, Metric tensor, Descartes coordinate system, Curvilinear coordinate system, Geometrical nonlinearity, Shell structures
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | Practical and/or problem-solving skills |
Class flow
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. Required learning should be completed outside of the classroom for review purposes.
