Stress on homogeneous mass .pdf
Webwhich acted upon the rock volume that is removed, are redistributed in the remaining rock mass. This results in local stress concentrations in the immediate vicinity of the opening. This phenomenon has been described by many authors. The calculations made are generally based on idealized conditions: isotropic, homogeneous materials. WebA simple relationship with a rational basis has been found to connect stress with strain for a series of homogeneous compression curves published by Cook and Larke. At large …

WebH= ˆg (here g is body force per unit mass) and h n = T. Accordingly, the conservation law requires the existence of a second rank tensor, the stress tensor ˙ (= ˙ ije ie j), satisfying T = n˙ (T j = n i˙ ij) Evidently, ˙ ije j is the stress vector T associated with a surface element having the unit outward normal n = e i at the point of ...

Web1. The soil mass is elastic, isotropic, homogeneous and semi-infinite. 2. The soil is weightless. 3. The load is a point load acting on the surface. The soil is said to be isotropic if there are identical elastic properties throughout the mass and in every direction through any point of it. The soil is said to be homogeneous if there are identical Webhomogeneous, linearly elastic continuum. If necessary, anisotropy and nonlinearity may be taken into account. Despite its limitation, the elastic analysis can be used to evaluate a …
WebThermal Stress. Temperature changes cause the body to expand or contract. The amount δT, is given by. δ T = α L ( T f − T i) = α L Δ T. where α is the coefficient of thermal expansion in m/m°C, L is the length in meter, T i and T f are the initial and final temperatures, respectively in °C. For steel, α = 11.25 × 10 -6 m/m°C.
