“…The mechanics and mechanisms of failure of hen eggs have been examined experimentally under contact loading conditions (MacLeod et al, 2005). In computational mechanics, the dynamic mechanical behaviour of the egg has been evaluated with Finite Element Analysis (FEA) from simple structural models (Coucke et al, 1998;Upadhyaya et al, 1986) to highly non-linear transient dynamic analysis, including the study of the rupture by impact loading (Nedomová et al, 2009b). FEA has also been used to evaluate the effects of variations in certain geometrical and material parameters of the egg on the structural and acoustic frequency response functions (Perianu et al, 2010) or even to study the microstructurecontrolled stability of selected eggshells of Indian dinosaurs (Srivastava et al, 2005).…”

With the aim of characterizing the different stress patterns in several egg types and evaluate the resistivity of the eggshell while impacting in free fall, experimental tests and computational simulations have been performed on eggs of the species Gallus gallus (domestic hen), Struthio camelus (ostrich), and Testudo sp. (tortoise). The different types of failure were determined for each taxa and stress distribution maps were recorded and correlated between experimental results and computational simulations using Finite Element Analysis (FEA). For domestic hens, the numerical results obtained in both tests have highly correlation with the results obtained in previous works; for ostrich (Struthio camelus) and tortoise (Testudo sp.) eggshells, the new data represent a very good tool to understand in further works the failure mechanisms of the eggshells. More interestingly, the present study provides the first empirical and mathematic results that allow establishing confident safety interval related to the laying process in the poultry industry.

“…For example, as early as 1986, Upadhyaya et al [3] measured the basic physical parameters of eggshells with the following results: the egg size and egg-shape index (the ratio of the major axis to the minor axis of an egg) had an impact on the static compressive strength of an egg; the smaller end of the egg, which served as the compression end, was able to bear a larger load under static compression [4]; the thickness of the eggshell greatly affected the maximum loading capacity; the curvature radius at the vertex of each end of the egg correlated significantly with the maximum loading capacity, which increased as the curvature radius increased [5].…”

It is important to study the properties and mechanics of egg drop impacts in order to reduce egg loss during processing and logistics and to provide a basis for the protective packaging of egg products. In this paper, we present the results of our study of the effects of the structural parameters on the mechanical properties of an egg using a finite element model of the egg. Based on Fluid-Solid coupling theory, a finite element model of an egg was constructed using ADINA, a finite element calculation and analysis software package. To simplify the model, the internal fluid of the egg was considered to be a homogeneous substance. The egg drop impact was simulated by the coupling solution, and the feasibility of the model was verified by comparison with the experimental results of a drop test. In summary, the modeling scheme was shown to be feasible and the simulation results provide a theoretical basis for the optimum design of egg packaging and egg processing equipment.
