An astronaut is performing a cartilage tissue engineering experiment in Mars in 2022. She wants to determine of the tissue engineered cartilage sample in a confined compression test. The specimen has a diameter of R and thickness h. This cartilage sample is inhomogeneous with two equally spaced zones: top , , and bottom 2, 2. Mars has a gravity of g*. With the top of the specimen is subjected to a displacement uo, determine the stress and strain distributions in the sample.
