Simulation of a remote field eddy current detector in eccentric thin-walled non ferrous tubes using a 3D finite-element program

This paper presents a non-linear analysis of three reinforced and two partially prestressed concrete solid beams based on a 20 node isoparametric element using an in-house 3D finite element program. Anon linear elastic isotropic model, proposed by Kotsovos, was used to model concrete behaviour, while steel was modelled as an embedded element exhibiting elastic-perfectly plastic response. Allowance was made for shear retention and for tension stiffening in concrete after cracking. Only in a fixed direction, smeared cracking modelling was adopted. The beams dimensions were 300x300 mm cross section, 3800 mm length and were subjected to combined bending, torsion and shear. Experimental results were compared with the non-linear predictions. The comparison was judged by load displacement relationship, steel strain, angle of twist, failure load, crack pattern and mode of failure. Good agreement was observed between the predicted ultimate load and the experimentally measured loads. It was concluded that the present program can confidently be used to predict the behaviour and failure load of reinforced and partially prestressed concrete solid beams subjected to a combined load of bending, torsion and shear.

Thin Walled

The experiment on joints of concrete filled thin-walled steel tube and the composite beam is carried out in 8 specimens, and mechanics performance of all type joints is concluded in general. The test results indicate that each joint has higher bearing capacity and better ductility performance. Solid65 and Shell181 Elements of ANSYS finite element program are adopted to simulate concrete and thin-walled steel sheet of composite beams and columns. Calculation results in theories proved conformity with the test in primary.

Lagrange Finite Element

Based on the Lagrange finite element method, a simplified computational technique for sliding interface in oblique penetration is proposed in the paper. By applying the 3D finite element program developed on this technique to numerical analog computation of ogive-noded steel rod penetrating in the aluminum target, a result which is consistent with that of A.J.Piekutowskis experiment can be reached. Hence it proves the rationality and validity of the program and method discussed in this paper and that the method is useful in the numerical study of penetration and perforation.

Warping Stress

Distributions of warping stress and deformation of modules with open-section and longitudinal stiffening plates were determined by a finite-element program. Eleven models of various stiffnesses and configuration but under the same torsional moment were studied. The loading and overall hull size are close to a containership of 38 000-ton loading capacity. The prismatic thin-walled beam analysis was performed on a model to compare the results from the finite-element approach. It has been found that the warping rigidity can be effectively increased by installing plates along the axis of the ship. The maximum warping stresses, which are usually found at the hatch corners of the wing boxes, are evaluated and compared.

Main Bridge

Main bridge of Nanning Bridge is taken as Research Object. Using the finite element program ANSYS, space finite element model of an arch bridge with two inclined thin-walled steel box ribs is build, stability safety factor of the bridge is calculated, eigenvalue buckling analysis and non-linear buckling analysis of inclined thin-walled ribs are carried out, and stability performance is discussed. The result shows that stability problems of this bridge mainly occur on the ribs and are out-of-plane buckling in general, and horizontal loads have greater influences on out-of-plane buckling. The calculation results can provide parameters for construction, health detection and maintenance in the operational phase of the bridge.
