matan 0.1.9

Material analysis package to plot or extract properties like tensile modulus etc.

**This package is still under development. Be aware of often updates, versions below 0.2 are pre-alpha, and can be changed without any warning, or without any backward compatibility! **

MaTan

Shortcut comes from Material Analysis - ultimately is should contains modules allowing user to calculate metals and polymers properties from tensile, HDT (polymers) and DSC tests, as well as the others. There are few similar packages in PyPI, but none of them I found good to me, so I wrote new one.

For now it includes:

• ISO:527-1 (polymers tensile test)
• File manager class

MatAn should have:

• sample class - the thermomechanical test manager [0.1.6v]
• files_manager to find and manage your data files [could be better, 0.1.9v]
• tensile_test object to manage the single tensile test [0.1.7v]
• tensile_tests object to merge the strain-stress curves, as well as calculate mean parameter values, with the errors [0.1.10v]
• Charpy's test manager
• DSC tests manager
• HDT test manager
• Rheological parameter manager
• Thermal/chemical modification manager
• Generate FEM material models for CAE software like ANSYS, CalculiX or OpenFOAM
• Generate matplotlib's barplots plots with just one command,
• use Polars to enhance the efficiency?

For now tensile test are partially implemented, in 0.1.9v tensile_tests objects cannot parse the results to obtain mean values of all the tests, as well as the errors, although this should be ready in 0.1.10v.

Abstract

Nowadays, Python is one of the most popular programming languages, even in non-informatics fields like mechanical engineering, due to its simplicity, and computer analysis solvers using FEM methods are part of almost all components, albeit access to material data is sometimes hard due to inadequate data in the datasheets, problems with calculations, inconsistent information, etc. To overcome this problem, the Python package was created, which allows to calculate the stress, strains, tensile modulus, and other properties from force and elongation data from a machine. For now, it includes only polymer tests according to the ISO-527-1 standard, but in the future, other standards should be included.

Moreover, the package would need a graphical user interface, which could make it even simpler to use and, more importantly, allow users to upload their obtained results into OpenAccess databases and export plastic strains, tensile modulus, and other properties needed to perform FEM and other numerical analysis. That could make FEM methods even more accessible, which would lead to a decrease in the use of unnecessary materials and, due to this, less CO2 pollution.
