elastic base
1.In this paper the Euler equation of the deflection of elastic thin plate is reduced to the equation with Schrodinger form by the principle of quantum electro-dynamics. Then we can obtain the general solution of deflection of elastic thin bending plate by the joint action of dynamical lateral pressure, force in central surface and external field on the elastic base.
2.The constitution and its effect on properties of elastic Nb-base alloy Nb-40Ti-5.5Al were examined by means of metallography,electron microscopy,X-ray dif-fraction analysis of chemically extracted phases and electron diffraction of thinfoil.
3.The Age Intensification of Gold-base Elastic Alloy Wire (Au-20Ag-30Cu)
4.Sphere indentation stress strain relation and contact damage for pure brittle and quasi bri ttle materials were investigated using steel spheres with different sizes as the indenter. Elastic modulus and the critical stress to cause damage were determined on the base of linear elastic relationship between the load and the contact area.
7.Using the multilayered elastic system theory,under the style of double rounds uniform load,considering the thickness value of pavement structure courses and the stiffness change as well as the difference of interface condition,this paper presents the influencing factors of shear stress peak value and its change rule for semi-rigid base course asphalt pavement structure.
8.Definition of strain seems to be simple,but it has great meaning A good definition of strain is usually solid base of deformation mechanics The elastic plastic mechanics is based on the Cauchy strain,but it has clear shortcomings,and more clear in the process of the large deformation limitations of Cauchy,Green strain and the accuracy of Koerbar Swainger strain are analysed simply by using the method of geometrical analysis,some examples are used to prove them
