Effect of hydrogen on fatigue crack propagation in bond weld fusion zone

On mesoscale, concrete is usually regarded as a three-phase composite, consisting of coarse aggregates, mortar and the bond zone between these two compositions. Among them, the mortar or aggregate can be regarded as isotropic materials, respectively.

在细观层次上，通常将混凝土看作由粗骨料、硬化水泥砂浆和界面粘结带组成的三相非均质复合材料，其中，硬化水泥砂浆或骨料可分别视为各向同性材料。

In the bond zone, the grains develop into the coatings in the form of epitaxial growth and the coatings have a good metallic bonding with the substrate.

熔合区晶粒以外延生长方式向熔覆层内部生长，基体与熔覆层呈现良好的冶金结合。

Due to internal cracking, the concrete around the steel bar can be regarded as a bond zone and an orthogonal anisotropic body as well.

认为钢筋周围的的混凝土由于内部开裂形成一粘结区，并可把粘结区域内的混凝土视为正交异性体。
