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 ...

On the determination of constitutive parametersin a hyperelastic model for a soft tissue [PDF]
, 2018 The aim of this paper is to study a model of hyperelastic materials and itsapplications into soft tissue mechanics. In particular, we first determine an unbounded domain of the constitutive parameters of the model making our smoothstrain energy function ...

Constitutive model for plasticity in an amorphous polycarbonate [PDF]
, 2007 A constitutive model for describing the mechanical response of an amorphous glassy polycarbonate is proposed. The model is based on an isotropic elastic phase surrounded by an SO(3) continuum of plastic phases onto which the elastic phase can collapse ...

Modelling, identification and application of phenomenological constitutive laws over a large strain rate and temperature range [PDF]
, 2013 A review of the different phenomenological thermo-viscoplastic constitutive models often applied to forging and machining processes is presented. Several of the most common models have been identified using a large experimental database (Hor et al., 2013)

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 ...

Strain Field Evolution and Constitutive Model of Coal considering the Effect of Beddings
Lithosphere, 2022 In order to study the bedding effect of coal and rock deformation, the surface deformation fields of coal and rock at different bedding angles were obtained by means of digital image correlation (DIC).

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 ...

A Model for Compression-Weakening Materials and the Elastic Fields due to Contractile Cells [PDF]
, 2015 We construct a homogeneous, nonlinear elastic constitutive law, that models aspects of the mechanical behavior of inhomogeneous fibrin networks. Fibers in such networks buckle when in compression.

Constitutive Model of Swelling Gypsum Rock
Advances in Civil Engineering, 2020 Swelling of soft rock, such as gypsum rock, is one of the major threats in tunnel engineering, causing structure damages such as floor heave and inward movement of sidewalls during construction and operation.
