Package: czmtestkit
The python packageczmtestkitworks parallel toAbaqus/CAEmainly to test user element subroutines of cohesive zone models.
Additionally, the package facilitates the implementaion of theMode Partitioning Methodfor mixed-mode characterization of interfaces proposed byMoreira et al., (2020).PrerequisitesEnsure that all the following requirements are satisfied.Requirements:Abaqus/CAE is available and can be opened with the following command from the command line.abaqus caeFortran compiler is linked to abaqus. If not, follow instructions byVictor Crespo-Cuevas (2021).Python and pip have been installed and can be run from the command line. If unsure, follow instructions inhttps://packaging.python.org/en/latest/tutorials/installing-packages/InstallRun the following command in a command window.python -m pip install czmtestkitIn case an issue arises, try the following command.pip install czmtestkitUse the following command to upgrade the package.python -m pip install --upgrade czmtestkitSoftware descriptionv1.1.0Update in type and functionality of 'nPoints' in doe_data for py_modules.run_sim function.v1.0.0Overview of current functionality of the package:Generate models and run finite element analysis of standardized tests for mixed-mode fracture characterization of interfaces using Abaqus/CAE. The asymmetric double cantilever beam (ADCB) and asymmetric single leg bending (ASLB) are currently available. The models can be implemented with cohesive zone elements at the interface.User element subroutines can be implemented to model the cohesive elements. Additionally, abaqus implementation of the cohesive zone using quadratic damage initiation and energy based linear damage evolution are available as a bench mark. Both BK criteria and power-law energy criteria are available.Sequentially run multiple test from a design of experiments (doe). However, running on cluster or parallel computing is not possible yet.Fetch history output from.odbfiles. Further post process the extracted data.Read data from converged increments in.msgfiles.Analytical models for the ADCB, ASLB and end notch flexure tests are also available and can be used to find fracture resistance curves from force-displacement curves or to predict force-displacement curves given the specimen dimensions and fracture properties.Examples are avaiable in thedocumentationand the package is onPyPI.
The code documentation for developers will be made available soon.Contributions are welcome.To ensure a safe environment, all contributors are expected to adhere to thecontributor guidelinesand the contributor covenant code of conduct.References[1]R.
