Definition: In physics, a thin clad is an object that has no thickness. In this context, "thinclads" refers to objects with very low density and negligible bulk modulus. These objects are often used in the study of materials science and mechanics as they represent the weakest link between matter and energy. Thinclads can be classified based on their size and shape. They can range from very small (less than 1/200th of a meter) to extremely large (>10
