Based on Genetic Algorithms, a multiparameter searching problem under a multi loadingcase condition is presented and some searching results are worked out.
It exhibits the viscous effect under dynamic loadingcase, and the effect strengthens with the growth of the micro-crack density induced by the meso-damage of material.
Based on the characteristics of air and water, and with the rule of similarity, initially we estimate the relationship of speeds of the these two objects under the same loadingcase.
