Phase field fracture modelling using quasi-Newton methods and a new adaptive step scheme
Philip K. Kristensen, Emilio Martínez-Pañeda
We investigate the potential of quasi-Newton methods in facilitating convergence of monolithic solution schemes for phase field fracture modelling. Several paradigmatic boundary va…
Mode II fracture of an elastic-plastic sandwich layer
E. Martínez-Pañeda, I. I. Cuesta, N. A. Fleck
The shear strength of a pre-cracked sandwich layer is predicted, assuming that the layer is linear elastic or elastic-plastic, with yielding characterized by either J2 plasticity t…
Cold Isostatic Pressing to Improve the Mechanical Performance of Additively Manufactured Metallic Components
Isidoro Iván Cuesta, Emilio Martínez-Pañeda, Andrés Díaz +1
Additive manufacturing is becoming a technique with great prospects for the production of components with new designs or shapes that are difficult to obtain by conventional manufac…
Gradient-enhanced statistical analysis of cleavage fracture
Emilio Martínez-Pañeda, Sandra Fuentes-Alonso, Covadonga Betegón
We present a probabilistic framework for brittle fracture that builds upon Weibull statistics and strain gradient plasticity. The constitutive response is given by the mechanism-ba…
Mode I crack tip fields: strain gradient plasticity theory versus J2 flow theory
Emilio Martínez-Pañeda, Norman A. Fleck
The mode I crack tip asymptotic response of a solid characterised by strain gradient plasticity is investigated. It is found that elastic strains dominate plastic strains near the…
On the Finite Element Implementation of Functionally Graded Materials
Emilio Martínez-Pañeda
We investigate the numerical implementation of functionally graded properties in the context of the finite element method. The macroscopic variation of elastic properties inherent…
