The paper presents research results on the influence of a regular perforation pattern on the modulus of elasticity (Young’s modulus) and on the strength properties of EN AW-5754 aluminium alloy sheet. Square and hexagonal array of cylindrical (in the plane of the sheet metal – round) holes was considered, maintaining a constant hole diameter and pitch value. The reference material was solid sheet metal (without perforation) of the same grade and thickness. It was found that hexagonal perforation pattern reduces the Young’s modulus and strength of the material to a greater extent compared to square array of holes, while maintaining a higher uniformity of the distribution of these parameters in the plane of the sheet metal. The comparative analysis of the elastic and strength properties of sheet metal with straight and hexagonal perforation was also carried out accounting for mass loss ratio.
