Elastic material solar container model

What is a constitutive model for elastic–plastic materials?

Conclusion A novel constitutive model for elastic–plastic materials is developed using scalar, conjugate, stress/strain, base pairs arising from a QR decomposition of the deformation gradient.

What is the elastic model?

The elastic model, shown in Figure 6.2, has been widely used in research. This model assumes that the normal force is generated by the elastic deformation of the stator during the rub-impact process and only includes the Coulomb friction force in the tangential direction.

Can the continuum elastic model be applied to cholesteric liquid crystals?

The continuum elastic model can, indeed, be applied to cholesteric liquid crystals. However, the absence of any mirror symmetry (chiral molecules) implies the presence of an additional term proportional to n • rot n in the expression (6.11) for the energy density [ 1 ].

How do we characterize a constitutive relation for an elastic–plastic material?

In order to characterize a constitutive relation for an elastic–plastic material, we therefore have to determine two quantities: (i) a family of elastic responses measured from the current natural configuration κ ̃ p, and (ii) an evolution equation for this natural configuration κ ̃ p.

Can hydrophilic polymer foam be used as a solar evaporator?

Wu, M. et al. Hydrophilic polymer foam as a monolithic interfacial solar evaporator with rapid self-cleaning, high evaporation efficiency, and salt resistance. Adv. Funct. Mater. 34, 2410729 (2024). He, J. et al. High-performance salt-rejecting and cost-effective superhydrophilic porous monolithic polymer foam for solar steam generation.

Which elastic perfectly-plastic material model is used for non-associative behavior?

Another elastic perfectly-plastic material model, the Drucker-Prager model, has been used with non-associative behavior (Hambleton and Drescher, 2008; Ozaki et al., 2015) for sandy soils and soft soil (sandy-loam soil) (Moslem and Hossein, 2014).
