Self-adaptive finite elements in fracture mechanics
Computer Methods in Applied Mechanics and Engineering, 1978Abstract A new finite element capability which permits the analyst to vary the order of polynomial approximation over each finite element is discussed with reference to its potential for application to stress intensity factor computations in linear elastic fracture mechanics.

Finite-difference approximation of energies in fracture mechanics
2000This paper provides a variational approximation by finite difference energies of functionals related to variational models in fracture mechanics for linearly--elastic materials in then framework of the Griffith theory of brittle fracture. The weak formulation of such a problem leads to functionals of the type \[ \mu\int_\Omega|{\mathcal E}u(x)|^2 dx ...

p‐convergent finite element approximations in fracture mechanics
International Journal for Numerical Methods in Engineering, 1978AbstractThe strain energy release rate (G) converges rapidly in finite element approximations in which the finite element mesh is fixed and the order of polynomial displacement interpolations (p) is increased. Numerical experiments indicate that the error inG is very closely estimated, even for small pand very coarse finite element meshes, by an ...

Mechanics of oblique fracture fixation using a finite-element model
Journal of Biomechanics, 1977Abstract An investigation of the mechanics of a compression-plated oblique fracture using a finite-element stress analysis model is described. Three aspects of compression plating are considered: the effect of tension in the plate on stresses at the fracture site, the effects of placing bone screws across the fracture surface at different angles to ...

Combination of finite element and reliability methods in nonlinear fracture mechanics
Reliability Engineering & System Safety, 2000Abstract This paper presents a probabilistic methodology for nonlinear fracture analysis in order to get decisive help for the reparation and functioning optimization of general cracked structures. It involves nonlinear finite element analysis. Two methods are studied for the coupling of finite element with reliability software: the direct method and
