【摘要】：分析了第十一屆全國周培源大學(xué)生力學(xué)競(jìng)賽初賽試題中第13題的圓環(huán)受力與變形的特殊性,明確了題中圓環(huán)發(fā)生大位移小變形,給出了其多種解法,指出了原型題解答對(duì)讀者的誤導(dǎo),并對(duì)大位移的影響、功與能的計(jì)算方法、中性軸的位置、應(yīng)力應(yīng)變分布等相關(guān)問題進(jìn)行了分析與討論,得到了圓環(huán)內(nèi)部受力與變形的過程.
[Abstract]:This paper analyzes the particularity of the stress and deformation of the ring in the 13th question of the 11th National Zhou Peiyuan College students Mechanics Competition, clarifies the large displacement and small deformation of the ring in the question, and gives a variety of solutions. This paper points out that the prototype solution misleads the reader, and analyzes and discusses the influence of large displacement, the calculation method of work and energy, the position of neutral axis, the distribution of stress and strain, and so on, and obtains the process of stress and deformation inside the ring.
