Constitutive model characterization and discovery using physics-informed deep learning [PDF]
Engineering applications of artificial intelligence, 2022 Classically, the mechanical response of materials is described through constitutive models, often in the form of constrained ordinary differential equations.

A new family of Constitutive Artificial Neural Networks towards automated model discovery [PDF]
arXiv.org, 2022 For more than 100 years, chemical, physical, and material scientists have proposed competing constitutive models to best characterize the behavior of natural and man-made materials in response to mechanical loading.

Application of a damage constitutive model to pile–slope stability analysis
Frontiers in Materials, 2022 Piles were regarded as elastic materials in the traditional numerical simulation. The elastic pile would not reflect the damage of the pile in engineering, which would misjudge the reinforcement effect of piles on slopes.

Determination of Constitutive Parameters of Crystalline Limestone Based on Improved RHT Model
Advances in Materials Science and Engineering, 2022 This study improves the RHT constitutive model based on some shortcomings, and the main improvements work are as follows: (1) hyperbolic function is used to make up for the deficiency of tensile strain rate enhancement factor of RHT constitutive model at

Modelling the Triaxial Compression Behavior of Loess Using the Disturbed State Concept
Advances in Civil Engineering, 2021 This paper investigates the triaxial compression behaviour of Q3 loess soil and the construction of a constitutive model accounting for the structural effect of loess on the basis of the disturbed state concept.

A generic physics-informed neural network-based constitutive model for soft biological tissues
Computer Methods in Applied Mechanics and Engineering, 2020 Constitutive modeling is a cornerstone for stress analysis of mechanical behaviors of biological soft tissues. Recently, it has been shown that machine learning (ML) techniques, trained by supervised learning, are powerful in building a direct linkage ...

A constitutive model for partially saturated soils
, 1990 The Paper presents a constitutive model for describing the stress-strain behaviour of partially saturated soils. The model is formulated within the framework of hardening plasticity using two independent sets of stress variables: the excess of total ...

A continuum constitutive model for FDM 3D printed thermoplastics
, 2020 Fused deposition modelling (FDM) is the most common additive manufacturing technology used for thermoplastic components. This layers-based manufacturing process results into direct links between printing parameters and the polymer mesostructure by means ...
