a volume element under stress The strain energy density u is defined as the strain energy per unit volume : 2 u xx (8.2.13) 2E The total strain energy in the bar may now be expressed as this quantity integrated over the whole volume, U udV , (8.2.14) V L which, for a...
Presented an analytical evaluation approach of linear elastic stress fields around a sharp V-notch.Developed a robust analytical evaluation approach of averaged elastic strain energy density.Interpreted the fatigue behaviors of welded components by the strain energy density approach.Proposed an engineering ...
local elastic strain energy densityIn a previous paper it was shown that the singular expressions for the elastic stress and displacements in the border region of a line crack are inadequate, generally speaking. This is nowhere more clearly demonstrated than for the case of the infinite sheet ...
The elastic strain energy of the series of orthorhombic I bronzes which occur in the Sn W O system has been calculated using the Fourier transform method. The results of these calculations are compared with microstructures and phase analysis carried out by transmission electron microscopy. The two ...
On the basis of hyperelastic material behavior various forms of the strain energy density function, depending either on the invariants of the right Cauchy-... S Ishikawa,A Tokuda,H Kotera - 《Journal of Computational Science & Technology》 被引量: 5发表: 2008年 Investigation of the influence ...
Uniaxial and five conventional triaxial compression tests were conducted on sandstone to obtain the evolution laws of the input energy density, elastic strain energy density, and dissipative energy density. The input and dissipative energy densities increased with increasing axial strain; the elastic strai...
In this work, the linear-elastic strain energy density concept is applied to assess the fatigue behaviour of bulk defect-afflicted components made of high-strength cast steel alloy G12MnMo7-4+QT. Based on analytical calculations, an energy-based design limit curve is derived which merges ...
