Outline and Purpose of the Course A material experiment for observing the mechanical properties and microscopic characteristics of rocks and metal materials and an observation of the structure of materials will be carried out. By completing this experiment, students will learn how to measure the mechanical properties of rocks and metal materials, how to observe structures, and how to use equipment related to measurement and observation.
Course Goals In this experiment, the aim is to be able to evaluate the Young's modulus, Poisson's ratio, uniaxial compressive strength, and the tensile strength of rocks and to determine the destruction condition of rocks, as well as the ability to observe the structure of rocks and metals using a microscope, and to be able to evaluate mechanical properties, such as yield stress, tensile strength, and the strain-hardening coefficient of metallic materials.
Schedule and Contents Overall description (1 time): An overall explanation will be given about the purpose of the class, the program, safety notes, and division into groups.

Rock material testing and destruction conditions (4.5 times): An outline of rock material tests, Young's modulus, how to obtain Poisson's ratio, uniaxial compressive strength, and the tensile strength calculation method will be explained. Additionally, starting with preparing rock specimens for each group, the uniaxial compression test of rocks and the strain measurement by strain gauge, the tensile test of rocks (compression test), the evaluation of Young's modulus and Poisson's ratio, and destructive condition determination will be carried out.

Tensile test and mechanical properties of metallic materials (4.5 times): The outline of the test method for metallic materials will be explained. Additionally, a uniaxial tensile test of steel material/aluminum alloy material will be conducted, and a calculation of the stress-strain curve as well as the evaluation and analysis of mechanical properties will be carried out.

Tissue observation of metal and rock (4.5 times): The method of observing the structure of metals and rocks and the usage microscopes will be explained. Regarding the observation of metallic structures, grinding and corrosion of the specimen is performed by each group, and the structure observation of crystal grains and so forth is conducted. As for the observation of the structure of rocks, the principle and usage of polarizing microscopes will be studied and the observation of rocks and minerals by means of polarized microscopes will be conducted; in addition, discussions on the observation results will be carried out.
Evaluation Methods and Policy Experiments are conducted for each group, and experiment reports are assigned for each topic. Grading will be based on 50% for efforts towards experiments and 50% for the experiment report.
Course Requirements It is desirable that students have taken “Basic Experiment on Resource Engineering.” It is also desirable to take “Field Practice of Resource Engineering,” “Rock Engineering,” and “Material and Plasticity” of the Resource Engineering course, which are open at the same time.
Study outside of Class (preparation and review) It is required to attend every class, work on the tasks handed out to each person in charge, and submit reports.
Textbooks Textbooks/References Others; prints will be distributed as necessary.
