Determination of safety factor for rock mass surrounding tunnel by sudden change of equivalent plastic strain in strength reduction method [PDF]

Geotechnical and Geological Engineering, 2021
Abstract A safety factor of rock mass surrounding the tunnel can be determined using the strength reduction method (SRM), however, it is the most important to solve the criterion of critical state. For the stability estimation of rock mass surrounding tunnel, there is need to discuss that it is preferable to use the same criteria for the slope,

Welding Deformation Analysis of Plates Using the Inherent Strain-based Equivalent Load Method [PDF]

Journal of the Korean Welding and Joining Society, 2010
IIn this study, used is the equivalent loading method based on the inherent strain to predict the welding deformation of panel members. Equivalent loads are computed from the inherent strain distribution around weld line, and then applied for the linear finite element analysis. Thermal deformation of panel members can be, of course, carried out through

The moment of inertia method to calculate equivalent ranges in non-proportional tension–torsion histories

Journal of Materials Research and Technology, 2015
A critical issue in multiaxial damage calculation in non-proportional (NP) histories is to find the equivalent stress or strain ranges and mean components associated with each rainflow-counted cycle of the stress (or strain) path.
