| Outline and Purpose of the Course | 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. | |||
| 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. | |||
| Schedule and Contents |
Orientation: 1 time. The course goals, schedule of this class, and various attention for safety are presented. Material testing and failure criterion of rock: 4.5 times. 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 sheet metals: 4.5 times. Overview of the testing for sheet metals is explained. A uniaxial tensile test of steel and aluminum alloy sheets is conducted, and then the stress-strain curves and the mechanical properties are evaluated. Metallographic observation and petrographic observation: 4.5 times. The metallographic observation for metal specimens and the petrographic observation for rock specimens are conducted. At the first step, observation procedures including how to use a microscope are explained. In the metallographic observation, every group makes a specimen and observes the metal crystal. In the petrographic observation, every student observes the thin sections of rocks using a petrographic microscope and learns how to identify minerals and rocks on thin sections. |
|||
| Evaluation Methods and Policy | 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 Requirements |
It is desirable that students take "Experimental Basics in Earth Resources and Energy Science, Laboratory" offered in the previous semester. It is also desirable to take "Materials and Plasticity", "Rock Engineering", and "Geological and Geophysical Survey, Field Excavation" for the Undergraduate Course Program of Earth Resources and Energy Engineering that are offered in the same semester. |
