... and the dynamic effects are examined when subjected to mechanical abuse from various loading directions. Second, an anisotropic finite element model that considers dynamic strain rates are developed, enabling it to accurately represent the mechanical response to both quasi-static and dynamic impact loads. At last...

... state, it is easy to cause battery abuse and accelerate the decline. To avoid this situation, the aging model with consideration of the battery degradation is coupled into the pseudo-two-dimensional (P2D) model. An aging effect-aware finite element model that can describe battery physical information...

... the constitutive behavior of the shell and jellyroll is determined through the experiments. The compression results of the finite element model have shown a good agreement with the experimental data, which demonstrates its effectiveness and accuracy. This research provides an effective and practical procedure...

... finite element model anisotropic mechanical abuse batteries Pouch type lithium-ion battery (LIB) has now been used in electric vehicles, smartphones, and computers. Mechanical abuse of LIB plays an important role in the safety issues to lead fire/explosion [ 1 – 4 ]. The mechanical integrity...
