- Experiment to determine the yield stress of the shrimp (defined as the stress at which the amplitude of the tail wiggling would have becomes less than a critical value) when crushed between two fingers showed that it occurred at a stress of about 10-5 N/m-2 (14.5 psi).
Rankine’s criterion predicts that shrimp failure would occur at
This corresponds to a depth of only 10m. Fortunately for all
lovers of crustaceans, this is not the case, and hydrostatic
stresses do not contribute to plastic flow.
