b. You would like to develop a new material to investigate if it would be appropriate for a fracture plate. Your goal is to analyze the behavior of the new material and not the plate itself (although that would likely be a good step to take in the future). You are planning to use a variety of mechanical tests to analyze your new material including a tensile test using a testing machine. As you are planning your test protocol, you are considering a couple of different shapes to use for the tensile test specimens you will use to collect the data (these shapes are pictured to the right). These specimens will be created using the new material and gripped on either end by the tensile testing machine. i. ii. iii. What are the experimental limitations of the two different test specimen shapes that are shown? What test specimen shape would be preferred to bypass these limitations? Please draw and explain your answer. What resources would you consult as you plan your testing protocol to determine the appropriate specimen dimensions for your tensile test specimens and loading rate for your test?

Question

I only need help with the part b please :)

Problem 3:
Proximal tibial plates are used for the treatment of fractures, osteotomies (cutting and
realigning bone), malunions, etc. of the proximal tibia. You have been informed of a fractured
proximal tibia plate similar to the image shown at the right (image source: DePuy Synthes). The
fracture in the plate occurred in the middle region near one of the empty screw holes, and
occurred 10 years after it was implanted into the patient.
a. Based on what you know about biomaterials and metals, describe two plausible modes of
failure for this plate. If needed, do some independent research on this topic to provide
some context. Please cite any sources that you use (APA style).
b. You would like to develop a new material to investigate if it would be appropriate for a
fracture plate. Your goal is to analyze the behavior of the new material and not the
plate itself (although that would likely be a good step to take in the future). You are
planning to use a variety of mechanical tests to analyze your new material including a
tensile test using a testing machine. As you are planning your test protocol, you are
considering a couple of different shapes to use for the tensile test specimens you will
use to collect the data (these shapes are pictured to the right). These specimens will
be created using the new material and gripped on either end by the tensile testing
machine.
