“…a mathematical equation is proposed to include the effect of ovality based on finite element collapse load results. In 2014, Gayan Rathnaweera et al investigated the performance of aluminium/Terocore hybrid structures in quasi-static three-point bending by experimental and finite element analysis study [12]. The performance of the hybrid structures was changed with percentage volume of Terocore foam and tube wall thickness.…”

An approach for estimating critical buckling strain of pipe subjected plastic bending is established in the present paper. A rigid -perfectly plastic material model and cross section ovalization of pipe during bending are employed for the approach. The energy rates of the ovalised pipe bending and the cross section ovalising are proposed firstly. Furthermore, these energy rates are combined to perform the buckling analysis of pipe bending, an estimation formula of critical buckling strain for pipe subjected plastic bending is proposed. The predicting result of the new critical buckling strain formula is compared with the available experimental data, it shows that the formula is valid. Keywords

Abstract. Study on analysis of interaction between the upper and lower is a hot research topic at present. It is produced with the rapid development of high rise buildings and computer technology. At present, super structure and foundation are paid more attention as engineering problem. In the design of building structure, the structure of the upper column as a separate structure is fixed on the basis of this traditional method without considering the influence of interaction between superstructure and foundation and foundation. The results were different from the actual, especially in high rise buildings. The unreasonable phenomenon is more and more obvious. Use the response spectrum method analyze of the horizontal structure of seismic dynamic. Compare and summarize the different strengthening layer setting scheme, structure displacement, internal force of the earthquake response, the following related conclusion: strengthening layer can effectively reduce the horizontal displacement of the structure, and with the increased number of layer reduction will increase. The dynamic response analysis under the earthquake provides some reference and suggestions for the seismic design of this kind of structure.

“…Rathnaweera et al [16] studied the performance of aluminum tubes and Terocore ® hybrid structures in quasi-static three-point bending. They observed that the bottom surface failure (tensile) from structures is one of the failure modes during bending and it occurred when the bottom surface of the outer tube reached the ultimate tensile strain.…”

Abstract:In order to characterize the deformation and true stress-strain relation of metal tubes, the geometry of tube walls after necking in uniaxial tension need to be determined. The paper investigated the necking process of metal tube. A large number of tensile tests and finite element analysis of 1Cr18Ni9Ti tubes with different sizes were conducted. It was found that the geometry of outer tube wall in the necking region can be described using a logistic regression model. The final geometry of the tube is determined by original tube diameter and wall thickness. The offset of tube walls are affected by two competing factors: volume constancy and necking. The offset distances of outer and inner walls are mainly affected by original wall thickness. The length of the necking zone is more influenced by original tube diameter. Tube elongation at fracture increases slightly as tube diameter gets larger, while the wall thickness has almost no impact on the elongation.
