Exact solutions are obtained for the deformations and the stress resultants in circularly curved beams and rings rsting on elastic foundations and subjected to general loads acting perpendicular to the plane of the initial curature of the beam.The governing equatios are develped from Hamilton's ...
The stress distribution across an inhomogeneous circular beam subjected to pure bending is considered. In previous treatments the spatial variation of the elastic stiffness has been modeled by a power law and here a slight generalization for the form of the elastic stiffness is given. It is shown...
MECH 303 Chapter4 4 -6 4.9 Effect of Circular Holes on Stress Distribution The effect of the hole is negligible at distances which are large in comparison with the dimension of the hole. To use polar coordinates is convenient, we convert the far boundary condition in rectangular coordinates ...
The application of a thermal source in non-contact forming of sheet metal has long been used. However, the replacement of this thermal source with a laser beam promises much greater controllability of the process. This yields a process with strong potential for application in aerospace, shipbuildin...
Mode I and mixed-mode I-II fracture properties of two bituminous mixtures, a Stone Mastic Asphalt and a Dense Bitumen Macadam, have been determined by means of three-point bending tests on notched specimens. Two specimen geometries, namely single-edge notched beam and semi-circular bending, have...
In order to calculate the frequencies, the equations of motion are obtained for metal/CFRP hybrid shafts. Several beam theories are evaluated, and differences between these theories in the prediction of the frequencies are also presented. It is found that, in certain cases, an optimum thickness ...
