Abstract: During a shear process the vibrational mode structure of a non‐crystalline model material will change under load. Thus, we expect an effect on the characteristic boson peak, which correlates with numerous features of disordered materials. In this paper, we perform shear deformation on two‐dimensional random network materials and investigate the distribution of their vibrational density of states (VDOS). Furthermore, the spectra of eigenvalues are studied in detail using similar approaches to investigate the eigenvectors and specifically their change due to load and plastic rearrangements.
