Modeling Some Mechanical Properties Distributions of Almond Using Weibull Function

Determining the mechanical properties of kernel is necessary for design of an almond cracker, peeler machines and almond shaker. Therefore, the objective of this research was tomodel the statistical distribution of the puncture force (F), deformation (D) and modulus of elasticity (E) for almond nut (N) and almond kernel (K) by using two- parameter Weibulldistribution function. This function gives the probability of an item operating for a certainamount of time without failure. The Weibull distribution is one of the most widely used lifetime distribution in reliability engineering. It is a versatile distribution that can take on thecharacteristics of other types of distributions, based on the value of the shape parameter (β) and scale parameter (η). The experimental data were compared with the predicted model inboth nut and kernel of almond. Both η and β parameters of the force, deformation andmodulus distributions were significantly influenced for kernels. In both almond kernels and almond nuts, the forces were better Weibull distributed than deformations and modules
