Hyper-surface for combined size, rate and temperature effects on material properties of pristine diamond
The prediction of the mechanical properties of key materials of different sizes under various loading rates and temperatures is essential to evaluating the integrity and durability of NEMS/MEMS devices under extreme working environments. To better understand the rate, thermal and crystal orientation effects on size-dependent material responses, molecular dynamics (MD) simulations were performed with the use of single crystal diamond (SCO) of various sizes under various uniaxial tensile loading rates and temperatures. In the MD simulations, the responses of SCD blocks under <100> and <110> tensions were studied. By combining the available experimental and simulation data, a hyper-surface was formulated to predict the effects of the combined size, rate and thermal effects on the material strength of pristine diamond.
