This study applies failure modes and effects analysis (FMEA) to high-dose-rate (HDR) skin brachytherapy using VLSAs to ensure safety and quality.
The numerical approaches also commonly utilize rock mass classification schemes to assign rock mass properties and apply failure criteria within the models.
Macro/micromulti-scale analysis based on the efficient implementation of the Generalized Method of Cells coupled with classical lamination theory was conducted to predict failure of composite laminates, applying failure criteria at the constituent level, including fiber, matrix and interface.
In geometrically nonlinear analysis two algorithms, indicating failure mechanisms, were applied: progressive failure analysis with material property degradation method and anisotropic Hill potential theory with assumption of perfect plasticity.
Whereas in Hashin's theory four different failure modes are considered, in the failure model applied only two failure modes are considered; the failure of fibers and matrix are not separated.
This study indicates that the failure assessment diagram of a material generated from tensile fracture plate configurations can be applied for failure pressure estimations of flawed pressure vessels.
Strong sanctions (fines and public disclosure) should be applied against failure in either respect.
Also, different schemes of cyclic loading were applied till failure.
Therefore, the application of these procedures might be questioned when applied to failure modes other than brittle fracture.
