A General Return-Mapping Framework for Fractional Visco-Elasto-Plasticity [PDF]

Fractal and Fractional, 2022
We develop a fractional return-mapping framework for power-law visco-elasto-plasticity. In our approach, the fractional viscoelasticity is accounted for through canonical combinations of Scott-Blair elements to construct a series of well-known fractional

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

Nihon 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.

Autograft maturation assessed by sequential quantitative MR T2 mapping and its correlation with patient-reported outcomes and return to sports during the first year after anterior cruciate ligament reconstruction [PDF]

Journal of Orthopaedic Surgery and Research
Background Although quantitative T2 mapping magnetic resonance imaging (MRI) is recognized as a non-invasive method for assessing graft maturity after anterior cruciate ligament (ACL) reconstruction, its longitudinal changes and association with clinical

Fully implicit numerical integration of the Yoshida-Uemori two-surface plasticity model with isotropic hardening stagnation

Fracture and Structural Integrity, 2021
The paper deals with the numerical investigation and implementation of the two-surface plasticity model (or bounding surface model). This plasticity theory allows to describe the deformation behavior under large strain cyclic plasticity and the material ...

Numerical Algorithms for Elastoplacity: Finite Elements Code Development and Implementation of the Mohr–Coulomb Law

Applied Sciences, 2021
Two numerical algorithms for solving elastoplastic problems with the finite element method are presented. The first deals with the implementation of the return mapping algorithm and is based on a fixed-point algorithm.

RETURN-MAP CRYPTANALYSIS REVISITED [PDF]

International Journal of Bifurcation and Chaos, 2006
As a powerful cryptanalysis tool, the method of return-map attacks can be used to extract secret messages masked by chaos in secure communication schemes. Recently, a simple defensive mechanism was presented to enhance the security of chaotic parameter modulation schemes against return-map attacks. Two techniques are combined in the proposed defensive

TOPOGRAPHIC MAPPING WITH MANIPULATOR ARM CAMERA IN LUNAR SAMPLE RETURN MISSION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
The topographic mapping of sampling areas, providing basic sampling environment information, is crucial in sample return mission. The fixed monitoring cameras were designed for mapping of sampling areas in fixed effective resolution.

Identifying robust bias adjustment methods for European extreme precipitation in a multi-model pseudo-reality setting [PDF]

Hydrology and Earth System Sciences, 2021
Severe precipitation events occur rarely and are often localised in space and of short duration, but they are important for societal managing of infrastructure.
