A Thermodynamically Consistent CZM for Low-Cycle Fatigue Analysis
Key Engineering Materials, 2018A cohesive zone model for low-cycle fatigue analysis is developed in a consistent thermodynamic framework of elastic-plastic-damage mechanics with internal variable. A specific fatigue activation condition allows to model the material degradation related to the elastic-plastic cyclic loading conditions, with tractions levels lower than the damage ...

The energy issue: A critical test for CZM
OCEAN 75 Conference, 1975As national concern has increased over the gap between domestic energy supply and demand, private interests and federal and state governments have been actively involved in discussions aimed at determining how energy supplies can be increased without causing severe negative environmental and socio-economic impacts.

Dynamic Crack Growth: Analytical and Numerical CZM Approaches
2008Service life extension of PWR vessels is an important issue for a number of nuclear operators. This aim is partially subjected to improvement of safety margins. These margins may be enhanced by acceptance of a limited amount of crack growth, starting from an initial flaw.

Crystal cracking of grain-gradient aluminum by a combined CPFEM-CZM method
Engineering Fracture Mechanics, 2021Abstract Gradient nanostructured metals attract extensive attention due to their excellent mechanical properties, while they are prone to microcracks during forming and servicing process and eventually develop into a sudden fracture. Actually, experimental studies show that microcracks occurred in both the grain boundary (GB) and the intragrain, but ...

CZM Act Amendments of 1976: Summary and Implications
OCEANS '76, 1976The Coastal Zone Management Act Amendments of 1976 greatly expand the 1972 Act. This paper briefly discusses each element of those amendments and their implication for coastal states and local governments as well as the private sector. Since no regulations have yet been developed for those amendments, opportunity for input through the Federal Register ...

Damage Evolution of the Interphase on C/SiC Composites with CZM Method
Applied Mechanics and Materials, 2012Considering thermal residual stress and initial matrix crack, the cylinder FEM analysis model for C/SiC tow was established. The cohesive element and damage criterions were introduced to simulation the initiation and propagation of interphase crack processes of C/SiC composites.

The Use of CZM for Coupled Fatigue/Plasticity Crack Propagation Simulation
2008In blading components, a large proportion of service life is taken up in initiating and growing surface or near surface short cracks through the Stage I fatigue regime, that is when the crack length is small compared to the scale of the crack tip plasticity.
