abstract = "For the design of batteries to sustain the crash
tests, the mechanical strength (force generated) on the
battery can be evaluated to understand its fundamental
effect on possible failure (such as breaking of
separator and short-circuit) of batteries. In this
perspective, this study proposed a holistic approach to
evaluate the maximum force generated on the battery
when subjected to the pinch-torsion test. The
fundamentals of the test are understood by formation of
Finite element analysis (FEA) model and validated based
on experiments. The inputs in FEA such as the
temperature, the displacement and the strain rate are
varied and the maximum generated force is observed on
the battery. The quantification of the finite element
data is further performed by an optimization approach
of GP. It was found that the GP model for an evaluation
of mechanical force on the battery is accurate. The
robustness in the model is validated by design of its
simulation for 10,000 runs. 2-D and 3-D surface
analysis suggests that the displacement due to
indentation is the most dominant followed by the
temperature and the strain rate. The findings from the
analysis can pave the way for design of new battery
that comprises of higher strength when subjected to the
crash tests",
