Finite element simulation of delamination growth in composite materials using LS-DYNA [PDF]
, 2009 In this paper, a modified adaptive cohesive element is presented. The new elements are developed and implemented in LS-DYNA, as a user defined material subroutine (UMAT), to stabilize the finite element simulations of delamination propagation in ...

A new cohesive model for simulating delamination propagation in composite laminates under transverse loads [PDF]
, 2008 In this paper, we propose a new cohesive model to stably and accurately simulate the\ud delamination propagations in composite laminates under quasi-static and low-velocity\ud impact transverse loads using comparatively coarse meshes.

Some features of the PPR cohesive-zone model combined with a linear unloading/reloading relationship [PDF]
, 2017 A loading/unloading/reloading process is applied to a cohesive zone where the model proposed by Park, Paulino and Roesler in 2009 is combined with a linear unloading/reloading relationship.

Cohesive zone modeling of creep–fatigue crack propagation with dwell time
Advances in Mechanical Engineering, 2017 In engineering application, a quantitative description of both fatigue and creep damage mechanisms is demanded for high-temperature alloy. This work employs the cohesive zone model to numerically simulate the crack propagation in a nickel-based super ...

An isogeometric approach to cohesive zone modeling [PDF]
International Journal for Numerical Methods in Engineering, 2010 AbstractThe possibility of enhancing a B‐spline basis with discontinuities by means of knot insertion makes isogeometric finite elements a suitable candidate for modeling discrete cracks. In this contribution we use isogeometric finite elements to discretize the cohesive zone formulation for failure in materials. In the case of a pre‐defined interface,

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]
, 2015 The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.
