Abstrakt EN: This paper describes uniaxial and biaxial tests of leather samples. The tests were conducted on non-standardized samples. The uniaxial test was performed on 100 samples. The biaxial test was done on 20 samples. The aim of the uniaxial test was to obtain a reliable value of the leather ultimate strength, on a large population of samples. Additionally, this test revealed the differences in the ultimate strength between two relative perpendicular directions of cut. The biaxial test was used to obtain the stress-strain relationship and the ultimate strength. The stress-strain relationship will be used in the future to improve the constitutive material model of the leather. The biaxial test was conducted under four logarithmically graded clamps separation speeds (1, 10, 100, 1000 mm/min).
