摘要:

In a compressed in‐series array of bodies having the same cross‐sectional area, the force is the same and the deformation the sum of that of the individual components. This concept, with certain simplifying assumptions, was used to develop a simple mathematical model with which the compressive force–deformation relationships of a finger–object array can be predicted on the basis of the compressive behavior of the individual components. The models’ applicability is demonstrated with experimental compression data of a human’s index finger and thumb and food specimens having concave upward or downward force–deformation curves (hot dog, cheddar cheese, and cream cheese), tested alone and in an in‐series array. This was done by representing the force–deformation curve of each component by a two‐parameter mathematical model whose form had been specially selected so that the force–deformation relationship of the array could be calculated by an explicit algebraic expression.
