Then, transient response of vertical displacement, vertical stress and pile-soil stress ratio of some nodes in the elastic subgrade are computed in one single loadcycle.
Many engineering structures are subjected to random loading in service. The loadcycle interactions can have a very significant effect in fatigue crack growth under variable amplitude loading.
许多工程结构在服役过程中受到随机载荷的作用,载荷循环之间的相互作用对裂纹扩展将产生明显的影响。

We'd done some load testing earlier, but this type of testing peaked near the end of the development cycle.
