We present here the simulations, using Gupta Potential, of gold cylinders under stress, showing the changes leading to the formation of chains at nano level. When one of these short chains is stretched, it transforms from a zigzag configuration to a straight one, passing through various qualitatively different phases and ultimately disintegrating via an interesting 'dimer' phase. Strain vs stress for all the cases are presented and young's modulus calculated. Using Density functional theory (DFT) study we have shown that doping of gold strand with Silicon or Carbon atoms increases its thermodynamic stability as suggested in a recent study.
