Evaluation of the stress singularities of plane V-notches in bonded dissimilar materials [PDF]
, 2008 According to the linear theory of elasticity, there exists a combination of different orders of stress singularity at a V-notch tip of bonded dissimilar materials. The singularity reflects a strong stress concentration near the sharp V-notches.

Procedia Structural Integrity, 2016 Abstract This paper characterizes the elastic-plastic-creep crack-tip stress fields under load and displacement control. The stress field has been calculated from finite element (FE) transient creep analysis under each load control condition and displacement control condition.

Wedge splitting test: Displacement field analysis by multi-parameter fracture mechanics [PDF]
, 2018 Multi-parameter fracture mechanics is nowadays quite extensively applied when cracked structures/specimens are investigated. The reason was that it has been shown that it can be helpful and bring results that are more accurate when for describing of ...

Propagation of cohesive crack in unsaturated porous media by use of XFEM method
E3S Web of Conferences, 2016 Various damage models have been presented to model the cracks. These models don’t simulate the discontinuity in displacement field; just see its effect on an upper level on stress field through damage parameter.
