Diamond anvil cells (DAC) are extensively utilized in the study of material properties at extreme conditions of pressures and temperatures. The pressures in excess of 400 GPa and temperatures in excess of 4000 K have been reported in DAC devices. Most studies on the optimization of diamond geometry and gasket materials used in diamond anvil cell devices have been carried out by trial and error using experimental high pressure data. This monograph addresses design and optimization issues in DAC using finite element modeling (FEM) and computational analysis. The computational approach is...
