- Splitting Mode-I fracture toughness of carbon fibers using . . .
In the pillar-splitting methodology, micropillars with circular cross-sections are prepared using FIB and then tested using a triangular pyramid to evaluate the load required to cause the micropillar fracture, which is correlated with the fracture toughness of the material using the CZFEM
- Multiscale Computational Analysis of Crack Initiation at the . . . - SSRN
Our findings highlight the importance of using concurrent multiscale models, such as a combination of CAC, crystal plasticity finite element (CPFE), and cohesive zone finite element method (CZFEM), to understand HE
- Investigation of fracture toughness and microstructure of micro-scaled . . .
High-resolution simulations using cohesive zone finite element methods (CZFEM), based on experimental observations, were conducted to gain a distinct insight into subsurface crack propagation and the development of fracture instability

- O. Erik Stracks research works | Sandia National Laboratories . . .
Numerical implementations of CZFEM are computationally costly since changes in topology must be resolved explicitly, and since contact algorithms must be used to prevent interpenetration of newly
- Peridynamic material particles | Download Scientific Diagram
The branching time for CZFEM (b) is the approximate time taken from Fig 16 in Song et al 10 Total time provided for the microelastic model (c) is taken from Fig 7 Table 7: Comparison of crack
- Continued Monitoring of Original I-94 Westbound Asphalt Overlay . . .
Mechanistic evaluations of the overlay test sections using the AASHTOWare PavementMETM, FlexPAVETM, IlliTC, Texas M-E Asphalt Overlay software (TxACOL), and high-fidelity finite element simulation using extrinsic cohesive zone models and thermo-viscoelastic asphalt mixture response (CZFEM) in the ABAQUS software package will be considered
- Investigating the mechanical behavior of multiscale porous ultra-high . . .
As such, this paper seeks to computationally characterize and understand the effective mechanical properties of porous UHTCs, specifically titanium diboride, and validate those results against experimental results so as to build confidence in the model
