  • 223 A study of residual stress analysis and optimality of stress distribution on bursting fruit

抄録

The plant seeds are moved in a variety of ways, for example, carrying on the window, insect or animal. Dispersion by bursting fruit is a typical moving way of plant seed that is self-active and independent of other creature . Fruit, which can burst powerfully and spread the seeds widely, are advantageous to expand breeding grounds of the plant in natural selection process. So, pericarp bursting mechanism of extant plants seems to be optimized mechanically and structurally. Bursting motion of pericarp depends on its mechanical stress in self-equivalent condition just before bursting. In this study, pre-burst stress distribution of fruit was evaluated by finite-element method and optimization technique.
