Determination of the stress and strain states and regression equations for different parameters in perforated plates with square holes placed in a parallel pattern, stressed with uniaxial traction

摘要

The paper compares the results of experimental tests and numerical modeling (carried out with the finite element method) carried out on the stress and strain state existing in a perforated plate with square holes placed in a parallel pattern, stressed with uniaxial traction. Also, regression equations are determined for various mechanical and energy parameters.
