Course Description

Fundamental experiments and microscopic observation of rock and metal materials are conducted. Through the experiments and microscopic observation, students can learn how to measure mechanical properties of these materials and how to use the equipments to carry out the experiments and observation.

Grading

Students are divided into several groups. Every student is asked to conduct the experiments and microscopic observation with group members and to make an experimental report individually for every theme. Grading is made by the attitudes to the experiments and the grade points of every experimental report. The grading weights of them are even.

Course Goals

The goal of this course is to master the evaluation method of mechanical properties for both rock and metal materials and the mineralogical observation method and the metallographic observation method.

Course Topics

Theme Class number of times Description
Orientation 1 The course goals, schedule of this class, and various attention for safety are presented.
Material testing and failure criterion of rock 4.5 Overview of the rock material testing, the method to obtain Young's modulus, Poisson's ratio, uniaxial compressive strength, and tensile strength are explained. First, in this theme, rock specimen is prepared. Second, uniaxial compression test is conducted. During the uniaxial compression test, strain measurement using strain gauges is performed, and the uniaxial compressive strength, Young's modulus and Poisson's ratio are determined. Third, Brazilian test is conducted and the tensile strength is determined. Finally, the failure criterion of the specimen is determined.
Tensile test and mechanical properties of metal 4.5 Overview of the testing for metal materials is explained first, and then a uniaxial tensile tests of steel and aluminum alloy are conducted. The true stress-true strain curve and the mechanical properties of the specimen are determined.
Mineralogical observation and metallographic observation 4.5 The mineralogical observation for rock specimen and the metallographic observation for metal specimen are conducted. Observation procesures including how to use a microscope are explained first. In the metallographic observation, every group makes a specimen and observe the metal crystal. In the mineralogical observation, student observe rock minerals using a mineralogical microscope. In addition, techniques to visualize the pores and cracks inside of rock are explained, and crack observation is conducted using a visualization technique.
