Popis: Evaluation of the mechanical and shielding features is performed for glasses with the composition xBi2O3-(80-x) TeO2-10GeO2-10B2O3 with different concentrations x = 40, 50, 60, and 65 mol%. The mechanical parameters are summarized utilizing the Makishima-Mackenzie model. The elastic moduli such as Young, bulk, shear, and longitudinal are computed. The obtained results depict the elastic moduli affected by the replacement TeO2 with Bi2O3 content. The maximum values of elastic moduli are 61.822, 40.706, 24.790, and 73.761 for Young, bulk, shear, and longitudinal, respectively, of the inspected glasses utilizing the Monte Carlo simulation code (MCNP-5). The mass attenuation coefficient (μρ) and the half-value thickness (HVT) were also calculated. The shielding ability is tested by comparing the mean free path of the studied glasses with the commercial glasses. Likewise, the accumulation of photons inside the glass’s material is determined using the BXCOM program. Finally, it can deduce the discussed fabricated glasses are suitable to apply in diverse applications of radiation protection.
