The applied load acting on the DFRC acts in the direction of the fibre axis—this action deforms the matrix material [14, 15]. At the fibre–matrix interface, the contact between the fibre and the matrix results in a s [14, 15]. Consequently, this induces stresses within the fibre [14, 15]. Since the external tensile load is applied in the direction parallel to the fibre axis, the mechanical response of the fibre is of an axisymmetric nature [14, 15]. Thus, the s and the induced rz and rr within the fibre are independent of / [14, 15].

In the macroscopic length scale, the deformation of most materials may be described by simple linear equations; a material undergoing small strain is often considered to behave linearly with regards to the force–displacement relationship. However, at the microscopic length scale, the same argument may not necessarily apply. For instance, silicon single crystal, which is a choice for the electronic industry, can easily undergo large strain, as compared to a beam made from a similar material [31].
