Experimental and numerical investigations on three-point bending collapse of thin-walled beams
Highlights 1. Three-point bending tests of single- and multi-cell thin-walled beams are performed; 2. Numerical simulations with shell elements and solid elements show different features; 3. When S/B is in the transitional region, the deformation is sensitive to the friction; 4. The constituent element method is proposed to predict the bending responses of beams.
Abstract Multi-cell thin-walled beams showed excellent energy absorption efficiency under various load conditions. However, the theoretical prediction of their bending resistance is quite a challenging task. In this work, the three-point bending collapse of thin-walled rectangular beams with single-, double-, and triple-cell sections is investigated experimentally and numerically. Two finite element schemes: the shell element scheme and the solid element scheme, are employed to simulate the experimental tests, and the features of the two schemes are compared. The influence of friction coefficients on the force response and deformation mode of the beams is analyzed. Finally, a constituent element method is proposed to predict the bending responses of multi-cell beams, and the feasibility of the method is demonstrated.
