Viscoplastic deformation analysis for spheroidal graphite cast iron by subloading-overstress model
Nihon Kikai Gakkai ronbunshu, 2020 The time-dependent elastoplastic deformation behavior, i.e. viscoplastic deformation behavior, is observed in solids and structures subjected to high temperature under monotonic and cyclic loadings.

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Viscoplastic Modeling the Evolving Mechanical Properties of Shotcrete 3D Printing Material
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT In recent years, additive manufacturing in construction (AMC) has gradually influenced the building industry by offering a faster and more efficient way to build with concrete. Unlike traditional methods that rely on molds, AMC deposits material layer by layer through an automated process, enabling new possibilities for custom designs and ...

A Phase Field Model for Rate-Dependent Ductile Fracture
Metals, 2017 In this study, a phase field viscoplastic model is proposed to model the influence of the loading rate on the ductile fracture, as one of the main causes of metallic alloys’ failure.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Nanoporous gold, with its hierarchical structure comprising interconnected networks on multiple length scales, poses significant computational challenges for traditional modeling methods. To solve this challenge, this study introduces a physics‐informed recurrent neural network (RNN) to model the homogenized material response of a diamond beam‐

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Seismic anisotropy is widely observed near subduction zones in the mantle transition zone and uppermost lower mantle, particularly along the western Pacific rim and tracks slabs geometries, implying an additional slab‐related source. Hydrous phases such as δ‐AlOOH and phase H (MgSiO4H2), which form a solid solution (δ‐H) and are stable in cool,

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates
Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Linear and nonlinear fractional hereditary constitutive laws of asphalt mixtures
Journal of Civil Engineering and Management, 2016 The aim of this paper is to propose a fractional viscoelastic and viscoplastic model of asphalt mixtures using experimental data of several tests such as creep and creep recovery performed at different temperatures and at different stress levels.

Bounds on internal state variables in viscoplasticity [PDF]
A typical viscoplastic model will introduce up to three types of internal state variables in order to properly describe transient material behavior; they are as follows: the back stress, the yield stress, and the drag strength.
