LOCALIZATION ANALYSIS OF AN ORTHOTROPIC MULTI-SURFACE PLASTICITY MODEL UNDER UNIAXIAL STRESS
Acta Polytechnica CTU Proceedings, 2020 Numerical simulations of masonry structures are often based on continuum macromodelling approaches that need constitutive laws able to phenomenologically reproduce the behavior of the material.

Computers and Structures, 2019 Abstract In this work we develop multi-surface plasticity model which can reproduce the inelastic behavior and failure modes of concrete in tension, compression and shear. The main novelty of the proposed concrete model can also capture all different phases of localized failure for massive structures, where the elastic behavior is followed by the ...

Multi-surface plasticity model for analysis of complex interlocking assemblies [PDF]
The drive for new masonry alternatives to energy-intensive, tensile-resistant ma-terials has led to complex interlocking geometries, but current design tools lack the structural insight to analyze these assemblies effectively. This paper presents Joint Layout Design (JLD), which extends multi-surface plasticity to model discrete, breakable ...

On the applicability of multi-surface, two-surface and non-linear kinematic hardening models in multiaxial fatigue [PDF]
Fracture and Structural Integrity, 2015 In this work, a comparison between NLK and Mróz-Garud’s multi-surface formulations is presented. A unified common notation is introduced to describe the involved equations, showing that the Mróz-Garud model can be regarded as a particular case of the NLK

Energy multi-scale method to analyze the scale effect of soil particles
Frontiers in Materials, 2023 As a common geological material, soil is a key aspect of construction engineering. Soil has typical multi-scale characteristics, but current multi-scale methods analyze these characteristics only in regard to geometric space.

Fatigue life assessment of a non-load carrying fillet joint considering the effects of a cyclic plasticity and weld bead shape [PDF]
Fracture and Structural Integrity, 2016 Fatigue life depends strongly on irreversible contributions that accumulate during cyclic loading and unloading of structures. However, the correct identification of the loading path in terms of uniaxial or multi-axial stress states, proportional or non ...

Formulation and implementation of a practical multi-surface soil plasticity model [PDF]
Computers and Geotechnics, 2020 Abstract This paper presents a new constitutive model for clay, for undrained monotonic and cyclic loading, that has been developed specifically for geotechnical design applications. The model employs a parallel Iwan approach, consisting of multiple elastic-perfectly-plastic micro models. Degradation of stiffness and strength during cyclic loading is
