Managed to get through a Ph.D. in nuclear physics without covering nuclear matter calculations (or I just don't recall it). My question is does nuclear matter have any shear strength, or is it like an ideal gas? What little I see of elementary calculations it's like a fermi gas so one would expect no shear stresses to speak of.

What are you calling nuclear matter? All ordinary matter consists of atoms with nuclei and electrons.

Okay, nuclear matter is a thing people study like for neutron stars and such where there are no free electrons. In ancient time (before quarks were more of a certainty) it's an $A = \infty$ where, $A$ is the atomic number nucleus, held together by a repulsive nuclear force and gravity. My question is does the current nuclear matter theory predict such stuff have a shear strength or is it more like a fermi gas?
