“…The required quality of the machined surface depends on the mechanisms of material removal and the kinetics of machining processes affecting the performance of the cutting tools [5]. The works of a number of authors [6][7][8][9][10][11][12], when reporting on milling of FRP, show that the type and orientation of the fibre, cutting parameters, and tool geometry have an essential influence on the machinability. Everstine and Rogers [6] have presented the first theoretical work on the machining of FRPs in 1971, since then the research carried out in this area has been based on experimental investigations.…”

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining any excessive cutting forces have to be avoided in order to prevent any waste product in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select process parameters necessary for an optimal machining. In this paper the effect of cutting conditions during milling machining on cutting force and surface roughness has been investigated. In particular the cutting force components have been analysed in function of the principal process parameters and of the contact angle. This work proposes experimental models for the determination of cutting force components for CFRP milling.

“…2 is essentially the same as in some previously-solved cantilever and column-buckling problems [2,3], and it is the only solution that involves no deformation of the material in the region X < 0. The same kind of deformation has been assumed to be valid in a machining problem [4] and in a problem involving the inflation of a central crack [5]; in the latter problem the deformation is different in detail but is similar to the present one in that it is assumed that there is no deformation in the region X < 0. Deformations of the type shown in Fig.…”

Introduction.In the present paper we consider a problem of finite plane deformation of an ideal fiber-reinforced material [ 1,2], A slab of material ( Fig. 1) is deformed by a load applied to its end. The problem has more than one statically and kinematically admissible solution. Two of these are shown in Figs. 2 and 3.In Sec. 3 we show that the deformation in Fig. 2 satisfies the minimum-energy criterion, while that in Fig. 3 does not. In fact, the energy is not even stationary at equilibrium for the deformation in Fig. 3. Minimum energy requires satisfaction of the stress equations of equilibrium, but the converse is not true. In Sec. 5 we show that the non-stationary energy at equilibrium is caused by the discontinuity line AD in Fig. 3. Thus, solutions with discontinuity lines are energetically inadmissible, and uniqueness is restored by using the minimum-energy principle.In Sec. 6 we turn to a different matter, which also involves consideration of the energy. We compute the energy dissipated when the slab separates from the support at point A, along a small segment of the boundary. We show that the energy dissipation does not take place at the crack tip A, but at the point D on the opposite boundary. We speculate on the possible implication of this result for fracture analysis.

“…In plane deformations of such materials [2], the kinematic constraint conditions are sufficiently restrictive, so that stress-strain relations often play only a minor role. For this reason, it is relatively easy to solve problems that would be intractible if the material were isotropic [3][4][5][6][7][8][9][10]. The relation of solutions from the idealized theory to solutions for slightly extensible materials is understood fairly well [11,12], Most of the existing work on plane deformations is discussed in a recent review article [13].…”

Introduction.Finite deformations of materials composed of long, strong fibers bonded together with a weaker matrix material can be studied by using the theory of ideal fiber-reinforced materials. This theory, which is the subject of a recent book by Spencer [1], is based on the idealizations that the fibers are continuously distributed and inextensible and that the composite is incompressible in bulk. In plane deformations of such materials [2], the kinematic constraint conditions are sufficiently restrictive, so that stress-strain relations often play only a minor role. For this reason, it is relatively easy to solve problems that would be intractible if the material were isotropic [3-10]. The relation of solutions from the idealized theory to solutions for slightly extensible materials is understood fairly well [11,12], Most of the existing work on plane deformations is discussed in a recent review article [13].In the present paper we discuss deformations of cylindrical bodies with fibers lying in cross-sectional planes. The fibers may be curved, but they have the same distribution on each cross-section. The body is stretched or compressed in the axial direction and then subjected to a further plane deformation. The axial stretching causes the cross-section to change shape. The theory of superposed plane deformations is not essentially different from the theory that applies when there is no stretching [2], if the stretched state is used as the reference state. Consequently, our main object is to determine the state of deforma-
