| 5. | In the layered model , transverse shear is ignored and material is assumed to be in a state of plane stress , and some other presuppositions are introduced , such as cracking of concrete takes place only in the plane perpendicular to the normal 但是钢筋混凝土板的非线性有限元研究目前一般都是采用分层法,将板分成若干混凝土层和钢筋层,忽略横向的剪切影响,各层混凝土材料按平面应力状态处理,这与真实情况有区别。 |
| 6. | With the increasing of raft foundation thickness , the hypothesis of kirchhoff will be invalid due to the incapable neglecting of transverse shearing deformation . the correct solution can not be deduced through theory of thin plate any more since the influence of transverse shearing deformation does not take into account 随着板厚度的增加,横向剪切变形不可忽略, kirchhoff假设不再成立,薄板理论已不能给出正确的解答,横向剪切变形的影响必须加以考虑。 |
| 7. | The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells , involving the effect of transverse shear and rotational inertia , are derived . by applying the reverberation method , the displacement and the resultant forces of the shell in the phase space are expressed . then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms . furthermore , the transient solutions are decomposed to the generalized ray integrals and computed numerically 分析了计及剪切变形和转动惯性的有限长正交异性圆柱壳中弹性瞬态波的传播问题,采用回传矩阵法,在相空间中给出了位移和内力的表达式。再利用laplace逆变换,得到正交异性圆柱壳受轴对称冲击作用时弹性瞬态波解,然后将其分解为若干广义射线积分之和,并用数值方法求解之。 |
| 8. | In this article , it is systematically introduced the kirchhoff ' s thin plate theory and the reissner ' s moderately - thick plate theory in which the transverse shear force has been taken into account further the different hypotheses of the two theories are analyzed then the difference of the two theories is found out 本文系统地介绍了kirchhoff薄板和考虑横向剪切力作用的reissner中厚板的相关理论,分析了薄板、中厚板理论的两种不同假设,找到了二种理论主要区别。 |
| 9. | A delaminated beam is divided into three areas and the displacement field of each area is a cubic function of the thickness coordinate . the continuity conditions of displacements and transverse shear stresses on the bonded interfaces , the delamination continuity on the debonded interfaces and the continuity conditions of displacements at the edges of debonded interfaces are assured 脱层梁被分为3个区,各区位移场为厚度坐标的三次函数,能满足层间位移和剪应力的连续条件、脱层界面的脱层条件和脱层边界点的位移连续条件。 |
| 10. | The rayleigh - ritz method is used to lead to analytical expressions for the stiffness and mass matrices and load vector as well as their sensitivities , which uses the simple polynomials to define assumed displacement functions , geometry and construction of wing structures . excluding some selected terms from the displacement functions or using stiff springs at the specified locations imposes boundary conditions . the accuracy of calculated results is improved by including transverse shear effects and using multiple sets of ritz functions in the analysis 它使用简单多项式作为ritz基函数、定义翼面的几何和结构参数,利用rayleigh - ritz方法导出翼面结构的刚度矩阵、质量矩阵和载荷向量及其灵敏度的解析表达式,通过排除位移函数中某些选定的项或在指定点使用约束弹簧施加各种边界条件,考虑横向剪切变形和使用多组ritz基函数改进分析的质量,使用等效蒙皮和等效夹芯技术提高计算效率。 |
