橋は厚さわずか10mmから30mm程度の薄い鉄(鋼)板の組み合わせでできています。そんな橋がなぜ25トンのトラックを何台も同時に渡すことができるのか,橋の強度についての基礎理論をある程度理解した上で,ペーパークラフトを製作して壊すことによってその仕組みを実感するコースです。50分程度,橋の構造と強くするための仕組みをスライドで説明します。それを踏まえて,桁橋(広瀬川に架かる牛越橋や澱橋と同じ形式)をペーパークラフトで製作し,それに重りを載せてどのくらい強度を持っているかを確認してもらいます。

Apr 2016   Diffuse bifurcations engraving diverse shear bands in granular materials
Shear bands with characteristic spatial patterns observed in an experiment for a cubic or parallelepiped specimen of dry dense sand were simulated by numerical bifurcation analysis using the Cam-clay plasticity model. By incorporating the subloading surface concept into the plasticity model, the model became capable of reproducing hardening/softening and contractive/dilative behavior observed in the experiment. The model was re-formulated to be compatible with the multiplicative hyperelasto-plasticity for finite strains. This enhanced constitutive model was implemented into a finite-element code reinforced by a stress updating algorithm based on the return-mapping scheme, and by an efficient numerical procedure to compute critical eigenvectors of elastoplastic tangent stiffness matrix at bifurcation points. The emergence of diamond-like and column-like diffuse bifurcation modes breaking uniformity of the materials, followed by the evolution of shear bands through strain localization, was observed in the analysis. In the bifurcation analysis of plane strain compression test, unexpected bifurcation modes, which break out-of-plane uniformity and lead to three-dimensional diamond-like
