Stress distribution beam on elastic foundation D A DILLARD Stresses in shear joints... 

The characteristic beam on elastic foundation stress distribution, as shown in Fig. 2 for the applied moment case, is frequently encountered in a wide range of adhesive bond situations. In addition to lap joints mentioned earlier, peel tests, moisture-induced stresses, and curvature mismatch situations all tend to exhibit this characteristic distribution. Clearly, the beam on elastic foundation has important qualitative and, in many cases, quantitative applicability to a host of adhesively bonded joints. 

The location of neutral axis is calculated considering a linear stress distribution, based on the assumption that the SCC beam behaves elastically until the panel yields. 

First, the elastic stress distributions of the un-notched specimens are obtained from a finite element analysis. For the PI un-notched specimen, the discrepancy between the finite element and the analytical result is very small (about 0.01%), thus validating the finite element calculation in terms of accuracy through the meshing and the type of element used. Therefore a similar calculation is conducted on the G1 un-notched specimen where the span to height ratio is smaller. The mismatch on the maximum stresses at the bottom and at the top of the beam between the finite element calculations and the analytical solution is 0.74% in tension and 0.79% in compression (and remains constant upon further mesh refinement). This estimation of the stress distribution is then used for the following evaluation of the stress intensity factor. 

For a nniformly distributed load on a straight beam (elastically stressed) with its left and right ends simply supported [1], the maximum fiber stress, or flexural strength, can be expressed by the following formnla ... 

Yielded zones in a three-point bend test when (a) The centre of the beam remains elastic and (b) a plastic hinge forms. The stress distributions, on the beam section under the load P, are shown for a material of infinite Young s modulus, and constant yield stress of 50 MPa. 

Skirt construction permits radial growth of pressure vessel due to pressure and temperature through the bending of skirt acting like a beam on an elastic foundation. The choice of proper height of the skirt support ensures that bending takes place safely. Finite-element methods can be effectively used to determine the stresses and deflections due to imposed pressure and temperature distribution. 

It is clear that all the specimens used to determine properties such as the tensile bar, torsion bar and a beam in pure bending are special solid mechanics boundary value problems (BVP) for which it is possible to determine a closed form solution of the stress distribution using only the loading, the geometry, equilibrium equations and an assumption of a linear relation between stress and strain. It is to be noted that the same solutions of these BVP s from a first course in solid mechanics can be obtained using a more rigorous approach based on the Theory of Elasticity.
