2D_ElastoPlastoDynamics: 2D dynamic non-linear structural mechanics dataset, with a non-linear non-local constitutive law

This dataset contains 2D dynamic non-linear structural mechanics with a non-linear non-local constitutive law.

 

The files format is PLAID, see the plaid documentation.

The variablity in the samples is the geometry (mesh). Outputs of interest are 3 transient fields: x and y components of the displacement at the nodes and the erosion status at the elements.

 

The dataset has a training set of size 1000 and a testing set of size 18. Outputs are not provided on the testing sets. 

 

Tips to access the data:

After decompressing the downloaded file:

from plaid.containers.dataset import Dataset
from plaid.problem_definition import ProblemDefinition

dataset = Dataset()
problem = ProblemDefinition()

problem._load_from_dir_(os.path.join(/path/to/data,'problem_definition'))
dataset._load_from_dir_(os.path.join(/path/to/data,'dataset'), verbose = True)

print("problem =", problem)
print("dataset =", dataset)
