It turns out that crack closure is the main reason for retardation, and cracktipblunting, crack deflection and strain-induced martensite would reinforce it.
The results of whole experiment indicate that applying electro-deposition technology will be an effective method of bluntingcracktip and healing crack.
从整个试验所得的效果来看，将来应用电沉积技术来钝化甚至愈合混凝土的裂纹是一种行之有效的方法。

The overload effects were controlled by various factors such as crackblunting, residual compressive stress ahead of the cracktip and crack closure induced by wake zone plasticity.
