Graphical modeling and computer animation of tensile deformation in polymer liquid crystals (PLCs)

We create polymer liquid crystals (PLCs) on a computer and subject them to constant-force tensile deformations. Molecular dynamics simulation procedur e is used and graphical models and animations of crack formation and propag ation as a function of time are generated. Special attention is given to re alistic rigid LC island geometry and the island spatial distribution in the material. Internal fracture processes can now be easily studied. As a resu lt of the numerous animations recorded, clear patterns in PLC crack initiat ion and propagation emerge. With the help of the animations, the structure of PLCs may be understood without having to resort to costly laboratory exp erimentation.
