To determine some mechanical properties of garlic bulb and its cloves, some mechanical tests was performed on a variety of Talesh local garlic at three levels of storage period with 70-day intervals. Mechanical tests are performed on three levels of loading speed and three levels of storage period. Compressive tests were performed on bulb, cloves, and on cylindrical samples taken from the tissue of garlic cloves. According to analysis of variance based on factorial experiment in randomized complete block design, the value of module of elasticity, maximum force required to rupture and toughness of cloves were measured respectively 2.762MPa to 7.091MPa, 105.043N to 167.27N and 62.358mJ/mm3 to 101.44mJ/mm3 and also the value of young module of elasticity, the maximum force required to rupture and toughness of cylindrical samples taken from tissue of garlic cloves were measured 3.368MPa to 6.981MPa, 12.606N to 25.762N and 0.173mJ/mm3 to 0.33mJ/mm3 respectively. The ranges of value of force required to loosen the bulb, while loading along the height and width direction, were measured 127.023N to 228.001N and 45.52N to 106.97N respectively.
