Prediction of elasto-plastic behavior of pressurized composite reinforced metal tube by means of Acoustic Emission measurements and theoretical investigation

Theoretical, numerical and experimental analysis of thick walled fiber metal laminate tube under axisymmetric loads

“…Introducing (20) into the first two equations of (2) it is possible to provide the relations for axial and hoop stresses, as measured by the strain gauges: (21) To finalize the strain gauge measurements, one can calculate the radial displacement, w, as:    r w (22) When comparing the results of all three analysis methods: analytical, numerical and experimental measurements, Table 3, it can be stated, that the observed outcomes are quite consistent.…”

Numerical Analysis of Stresses on Layer-by-Layer Basis in FML Composite Cylinder Subjected to External Hydrostatic Loading

“…Static buckling was performed to determine the pre-buckling deformation. The linear Eigen value buckling analysis was used to determine buckling load-initial/critical load at which a structure becomes unstable and buckled mode shapes-the characteristic shape associated with a structure's buckled response [1]. It only predicts the pre-buckling deformation, but does not solve the magnitude of deformation post buckling [5].…”

“…Fiber Metal Laminate (FML) composite cylinders possess superior properties of both metals and fibrous composite materials making them most suitable for oil and gas storage, transportation, high pressure working conditions etc. [1]. During the manufacturing process of FML cylinders using filament winding method, residual stresses are induced in between the layers of the composite cylinder due to mismatch of the physical, mechanical and chemical properties of the matrix and reinforcement [2] [3].…”
