Abstract/Summary

 

This section will include the following (and maybe some other stuff I missed?)

  • Highlight of results

  • What test we are doing (tensile, compression anvil pendulum etc.)

  • Some more specific information we missed, for example, we used our own equipment, we didn’t have the correct equipment so we had to choose something else, something that may have messed up our test results? (feel free to add other things you believe are important to note)

  • Lack of test specimens for the standard quantity that standards require?

  • Link to ASTM Standard summary?


 

Introduction

  

The purpose of this test is to determine the shear strength of our materials. The way we will be going about this is by performing a 3-point bend test on our own sandwich constructions and then calculating the shear strengths from the values we obtained from the test itself. We will be emulatinghttps://uwmidsun.atlassian.net/wiki/spaces/MECH/pages/2066317358/ASTM+C393+Standard+Test+Method+for+Shear+Strength for this particular test. From this test, we want to make sure that our methods for sandwich construction are sufficient and that they can withstand our uses. We will be noting the maximum compressive forces and failure modes that we receive during the test. The failure modes that we expect will probably most likely be local core crushing since it is a compression test. (explain to me what relevant results include and some feedback on this paragraph would be greatly appreciated).

Test Specimen Prep

 

Here, we can outline how we prepared the specimen along with the dimensions we went with, sorta similar to what Tommy did here in the specimen prep section:F2020 - Bottom Panel Structural Evaluation?

This isn’t what actually happened, I just want to show how the organization would look

Failure mode

Picture of failure mode

During the test, we faced a debonding failure mode during the test for specimen number 2. (area and location of failure? please explain to me what this means).

(Please tell me how I could better word this, would appreciate the feedback)

Specimen number 2

During the test, we faced a debonding failure mode during the test for specimen number 2.

(Please tell me how I could better word this, would appreciate the feedback)

Specimen number 2

 

Pls tell me which one you think looks better? After putting it in the table, I’m leaning towards that.

Discussion

 

Here, we can just explain what went/think went wrong and how we could’ve maybe avoided it if anybody wants to read this for future reference?
