However , the interparticle friction did not appear to have a significant effect on the magnitude of the lateral stress developed during the uniaxial compression 然而,顆粒間的摩擦對(duì)軸向加載時(shí)系統(tǒng)產(chǎn)生的水平應(yīng)力沒(méi)有很強(qiáng)的影響。
Based on the theoretical contact mechanics , the numerical simulations demonstrated that the axial stiffness during compression was sensitive to both the amount of plastic deformation and the interparticle friction occurring at the contacts within the assembly of particles 研究發(fā)現(xiàn):彈塑性球顆粒系統(tǒng)在加載時(shí)其軸向剛度對(duì)顆粒間產(chǎn)生的塑性變形量及顆粒間的摩擦均很敏感。
