Determination of the creep behavior of potato tubers during storage period by means of uniaxial and triaxial creep tests.

The analysis of static forces is essential in the storage of agricultural products because these forces are applied in fruits, vegetables, or grains that can lead to their permanent deformation. This mechanical damage increases the product waste. Given that the potato tuber is surrounded by other tubers in the storage, then every tuber is pressurized from all sides or so-called triaxial stress.
