The Castillo de San Marcos fort in St. Augustine, FL, has withstood numerous wars and hurricanes for over 300 years. Interestingly, during military sieges it was discovered that the fort walls did not shatter upon impact, but instead absorbed the cannonballs. The endurance of this fort is attributed to a native rock, called coquina, from which it was constructed. Quasi-static and high strain rate uniaxial compression experiments were conducted on coquina and two other materials (sandstone and a…
