ABSTRACT
The article investigates the potential application of CAD systems for predicting the mechanical
properties of structural materials by comparing experimental test results with data from
nonlinear simulations. Real-world tests were conducted using a universal testing machine and
specimens manufactured according to ASTM E8M standards, while SOLIDWORKS 2022
Professional with the SOLIDWORKS Simulation module was employed for modeling.
Special attention was given to optimizing simulation parameters, including mesh configuration,
time steps, and the selection of the “Nonlinear Elastic” material type, which enabled
the accurate representation of complex material behavior under tensile loading. The comparison
of experimental and simulated data revealed an error margin of 4 % - 7 %, confirming
the high accuracy of the modeling approach. Observed deviations are attributed to simplifications
in the stress-strain curve and limitations of the model. The study highlights the promising
role of CAD systems in forecasting the mechanical characteristics of both existing and
novel materials with unique properties, while also underscoring the need for further refinement
of modeling techniques to account for real-world physical phenomena.
