The SHSS is analyzed using the surface stress extrapolation method, the stress linearization method and the 1 mm stress method.
Another method (the stress averaging approach) achieves the same effect using a fictitious radius concept.
The examinations were executed by constant load amplitude method, the stress ratio was R= 0,1, and f= 20 Hz frequency was used during the whole tests.
Employing the finite Mellin transform method, the stress and electrical displacement at all fields of the piezoelectric finite wedge are derived analytically.
In the Stress-Glut method, the stress concentration is blunting (Dalguer and Day, 2006).
Various methods for fracture prediction have been proposed in previous literature, such as the conventional logging method, the stress field method, the principle curvature method, the geostatistical method, etc. (e.g., Savage et al. 2010; Zahm et al. 2010; Jiu et al. 2013).
Some approximate methods for the stress state predictions for laminated plates are presented here.
Unlike the previous version of the enhanced assumed strain method, the stresses can be evaluated from variational formulation within variational framework.
The fractured medium is modeled with the extended finite element method, and the stress intensity factor is calculated by the simple, though sufficiently accurate, displacement extrapolation method.
MAM can improve the accuracy of Harman and Wang method, solve the stress asymmetry, obtain secondary peak of shear stress, and increase the highest peak of stress.
