Abstract: In this study, the mechanical characteristics of two-dimensional materials Titanium $$1T\text{-}TiX_{2}$$ and Vanadium $$1T\text{-}VX_{2}$$ $$(X=S,\ Se,\ Te)$$ were determined by the atomic finite element method (AFEM). The Stillinger-Weber potential function was used to describe the binding potential of the atoms in the tensile test simulation of these materials. The results determined the mechanical characteristics of the materials: the two-dimensional elastic modulus $$E.t$$ has a value in the range of $$40.98\div86.84\ \text{N/m}$$; the Poisson's ratio is in the range of $$0.418\div0.234$$; the maximum stress $$\sigma.t$$ is in the range of $$4.75\div13.02$$ and the strain at maximum stress $$\varepsilon$$ is in the range of $$21.3\%\div31.3\%$$. The study also showed that the two-dimensional elastic modulus when stretched in the zigzag direction (ZZ) is approximately equal to that when stretched in the armchair direction (AC), so these materials can be considered isotropic. These results provide a basis for their practical applications such as electronics, spintronics, and energy-related fields.
