Phase-field modeling of brittle fracture with multi-level hp-FEM and the finite cell method
, 2018 The difficulties in dealing with discontinuities related to a sharp crack are overcome in the phase-field approach for fracture by modeling the crack as a diffusive object being described by a continuous field having high gradients.

Advanced Engineering Materials, EarlyView.Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Scripta Metallurgica et Materialia, 1995 Abstract A two-dimisnsional analysis of crack propagation in anisotropic single crystal has revealed that the cleavage path depends on the shape of the γ-plot. Consequently, for a given notch plane the fracture path has been predicted to depend on the notch front orientation.

Advanced Engineering Materials, EarlyView.The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Arbitrary bi-dimensional finite strain crack propagation [PDF]
, 2009 In the past two decades numerous numerical procedures for crack propagation have been developed. Lately, enrichment methods (either local, such as SDA or global, such as XFEM) have been applied with success to simple problems, typically involving some ...

Influence of local mechanical loadings paths on the oxidation assisted crack initiation of alloy 718 [PDF]
, 2011 At high temperatures, alloy 718, like many other nickel-based superalloys, is sensitive to an oxidation-assisted intergranular crack (OAIC) growth mechanism.
