Case Study: Shock Test Solutions

**Presenter:** Shimpei Yamashita, Instron Japan, Materials Testing Division **Seminar Summary:** When we think of a "three-point bending test," we typically imagine a test where a static compressive load is applied. By placing a specimen in a bending fixture and dropping a tap (impact rod) from a certain height to apply an impact, we can conduct a dynamic bending impact test. Furthermore, these tests can be performed not only on thin sheets and dumbbell specimens but also on components (finished parts), allowing for tests that are more representative of actual usage conditions. This seminar will introduce the "three-point bending" and "component" impact tests. **Target Audience for the Seminar:** - Those considering testing not only thin sheets and dumbbell specimens but also large finished parts. - Individuals who are hearing the term "three-point bending impact test" for the first time. - Those who want to safely conduct impact tests on large specimens and observe the impact behavior. - Customers considering the Instron 9400 series and Bluehill Impact software.

**Presenter:** Shimpei Yamashita, Instron Japan, Materials Testing Division **Seminar Summary:** Are you familiar with the "CAI" test? It is a common testing method for composite materials primarily used in aircraft wings and is defined by testing standards such as ASTM. In Japanese, it is referred to as the post-impact compression test, which involves conducting two tests: the drop weight impact test and the static compression test. I will explain why such tests are necessary and how they are actually carried out. Additionally, I will provide specific examples related to the compression impact test. **Target Audience for the Seminar:** - Those who have heard of the CAI test but want to know how it is specifically conducted. - Those interested in how to capture the dynamics of the impact test using high-speed cameras. - Those who want to learn about specific examples and fixtures related to the compression impact test. - Customers considering the Instron 9400 series and Bluehill Impact software.

**Presenter:** Shimpei Yamashita, Instron Japan, Materials Testing Division When it comes to peel tests and tensile tests, many people may think of "static tests." While it is common to conduct tests at low speeds, in actual usage environments, instantaneous impacts occur, making evaluations through "dynamic tests" such as peeling or tensile testing important. This seminar will focus on peel impact tests and tensile impact tests conducted using a drop weight impact testing machine, and will also introduce real-world examples of industries where these tests are performed. **Target Audience for the Seminar:** - Those who want to understand why dynamic peel impact tests and tensile impact tests are necessary. - Those who want to know what standards exist and under what testing conditions they are conducted. - Customers considering the Instron 9400 series and Bluehill Impact software.
