Extended subloading surface model based on multiplicative finite strain elastoplasticity framework: constitutive formulation and fully implicit return-mapping scheme

open access: yesNihon Kikai Gakkai ronbunshu, 2017
This paper presents a finite strain elastoplastic constitutive model incorporating the extended subloading surface concept within the unconventional plasticity framework for cyclic loadings. This is a reformulated and extended version of the small strain

A re-formulation of extended subloading surface model for cyclic plasticity within small strain framework: hyperelastic-based formulation and fully implicit return-mapping scheme

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This paper presents a re-formulation of the extended subloading surface model within the ‘unconventional plasticity’ concept applicable to cyclic loadings. The small strain theory is adopted in the model formulation.

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.

Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (2st Report, Deformation analyses of machine elements)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The implicit stress integration algorithm was devised in the first report by formulating the return-mapping based on the cutting-plane projection and the consistent tangent modulus tensor due to the numerical method for the subloading surface model.

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.
