Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (1st Report, Formulation of return-mapping)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The subloading surface model possesses the automatic controlling function to pull back the stress to the yield surface. However, this function is not concerned with the subyield state, i.e.

UAS FOR GEO-INFORMATION: CURRENT STATUS AND PERSPECTIVES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Recent and ongoing developments of state-of-the-art sensor technologies have resulted in smaller and lighter photogrammetric cameras with IMU, lidar scanners and other sensors that can now be integrated with and mounted on the larger Light UAS.

Elastoplastic analysis by return-mapping method with rigorous loading criterion for extended subloading surface model

open access: yesNihon Kikai Gakkai ronbunshu, 2019
The extended subloading surface model is capable of describing cyclic loading behavior accurately. The elastoplastic deformation analysis by the finite element analysis can be executed efficiently by the complete implicit stress integration method with ...

Return to return point memory [PDF]

open access: yes, 2003
We describe a new class of systems exhibiting return point memory (RPM) that are different from those discussed before in the context of ferromagnets. We show numerically that one dimensional random Ising antiferromagnets have RPM, when configurations ...

Development of a workplace intervention for sick-listed employees with stress-related mental disorders: Intervention Mapping as a useful tool

open access: yesBMC Health Services Research, 2007
Background To date, mental health problems and mental workload have been increasingly related to long-term sick leave and disability. However, there is, as yet, no structured protocol available for the identification and application of an intervention ...

Assessing the capacity of large-scale hydrologic-hydrodynamic models for mapping flood hazard in southern Brazil

open access: yesRBRH, 2022
Mapping flood risk areas is important for disaster management at the local, regional, and national scales. The aim of this study was to evaluate the ability of large-scale models to obtain flood hazard maps.

A Return Mapping Algorithm for Nonlinear Yield Criteria with the Equivalent Mohr–Coulomb Strength Parameters

open access: yesAdvances in Civil Engineering, 2020
This paper proposes a modified return mapping algorithm for a series of nonlinear yield criteria. The algorithm is established in the principal stress space and ignores the effect of the intermediate principal stress.

Mapping snow depth return levels: smooth spatial modeling versus station interpolation [PDF]

open access: yesHydrology and Earth System Sciences, 2010
For adequate risk management in mountainous countries, hazard maps for extreme snow events are needed. This requires the computation of spatial estimates of return levels. In this article we use recent developments in extreme value theory and compare two

Landing Site Mapping and Lander Localization for Chang’e-5 and Chang’e-6 Lunar Sample Return Missions [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Chang’e-5 and Chang’e-6 are lunar sample return missions in China’s lunar exploration program. In these missions, high-resolution landing site mapping and lander localization were performed to support mission operations and scientific ...
