Elastoplastic analysis by complete implicit stress-update algorithm based on the extended subloading surface model

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Elastoplastic analysis of solid structures under cyclic loadings is increasingly required in recent years. To this end, it is necessary to adopt elastoplastic model capable of describing cyclic loading behavior and to employ stress integration algorithm ...

A 3D Interferometer-Type Lightning Mapping Array for Observation of Winter Lightning in Japan

open access: yesRemote Sensing, 2023
We have developed and deployed a 3D Interferometer-type Lightning Mapping Array (InLMA) for observing winter lightning in Japan. InLMA consists of three broadband interferometers installed at three stations with a distance from 3 to 5 km.

Airborne Lidar: Advances in Discrete Return Technology for 3D Vegetation Mapping

open access: yesRemote Sensing, 2011
Conventional discrete return airborne lidar systems, used in the commercial sector for efficient generation of high quality spatial data, have been considered for the past decade to be an ideal choice for various mapping applications.

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.

Smooth finite strain plasticity with non-local pressure support [PDF]

open access: yes, 2010
The aim of this work is to introduce an alternative framework to solve problems of finite strain elastoplasticity including anisotropy and kinematic hardening coupled with any isotropic hyperelastic law.

A return mapping algorithm for isotropic elastoplasticity

open access: yesInternational Journal for Numerical Methods in Engineering, 1994
AbstractA return mapping algorithm is presented for the numerical time integration of the constitutive equations for elastoplasticity with isotropic yield surfaces, constructed from all three invariants of the stress tensor. Based on the first‐order backward Euler difference formula (BDF), the governing equations for the stresses are solved in the ...

RETURN MAPPING FOR CREEP AND PLASTICITY SPLIT [PDF]

open access: yesBlucher Mechanical Engineering Proceedings, 2014
Within the range of validity of the small strain theory, the strain is additively decomposed in an elastic or reversible strain and an inelastic or irreversible strain.The inelastic strain consists of a plastic component quickly developed under loading, and a viscous or creep component develops that slowly under loading.Most frequently, both components

Integration algorithms of elastoplasticity for ceramic powder compaction [PDF]

open access: yes, 2014
Inelastic deformation of ceramic powders (and of a broad class of rock-like and granular materials), can be described with the yield function proposed by Bigoni and Piccolroaz (2004, Yield criteria for quasibrittle and frictional materials. Int.

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.
