A Griffith theory for fatigue from Delft group?

I came across an interesting theory for fatigue crack propagation from collegues in Delft, I think the group of prof Benedictus, but I have mixed feelings about it, because while there seems to be something very interesting experimentally, there seems to be some confusion between concepts of energy balance like Griffith seminal theory of fracture (which do not apply in fatigue) and Paris type of law, which are only weak forms of power law scalings which depend on all dimensionless parameters of the problem, so that C and m in Paris are not material constants, and there is no energy balance

On the Afferrante-Carbone theory of ultratough peeling

I attach a preprint of a note on the elegant and interesting and simple theory by Afferrante and Carbone on ultratough peeling of an elastic tape from a viscoelastic substrate.   Any comment is most welcome.   Regards, MC

Postdoc openings on metal additive manufacturing at the National University of Singapore

Dr. Wentao Yan's group at the Department of Mechanical Engineering, National University of Singapore (NUS), focuses on metal additive manufacturing: computational modeling, experimental investigation and data analytics.
There are two openings for postdoctoral fellows available immediately. The candidates are required to have expertise in one of the following areas: 1) high-entropy alloys; 2) hot cracking and thermal stress; 3) multiphase/fluid-particle flow modeling. The expertise on additive manufacturing is a plus but not a must.

Geometrically exact elastoplastic rods -determination of yield surface in terms of stress resultants

This work addresses the determination of yield surfaces for geometrically exact elastoplastic rods. Use is made of a formulation where the rod is subjected to an uniform strain field along its arc length, thereby reducing the elastoplastic problem of the full rod to just its cross-section. By integrating the plastic work and the stresses over the rod's cross-section, one then obtains discrete points of the yield surface in terms of stress resultants. Eventually, Lamé curves in their most general form are fitted to the discrete points by an appropriate optimisation method.

A phase field formulation for dissolution-driven stress corrosion cracking

Dear iMechanicians, I hope that our latest JMPS paper is of interest to you. We show how the phase field paradigm can be extended to model localised corrosion (aqueous electrolyte-solid interface) and the associated damage mechanisms.

The mathematical foundations of anelasticity: Existence of smooth global intermediate configurations

A central tool of nonlinear anelasticity is the multiplicative decomposition of the deformation tensor that assumes that the deformation gradient can be decomposed as a product of an elastic and an anelastic tensor. It is usually justified by the existence of an intermediate configuration. Yet, this configuration cannot exist in Euclidean space, in general, and the mathematical basis for this assumption is on unsatisfactory ground.

New article on inelastic homogenization through machine learning

I would like to share another article from my group just published in CMAME. I think this is an interesting approach towards the automatic generation of constitutive laws for arbitrary microstructures:

https://authors.elsevier.com/a/1bxlSAQEIt1ls

The article focuses on how to systematically create constitutive laws using only:

1) Available microstructural models

2) Machine learning techniques
