Assuring conformity regarding the number, spacing, and location of rebars is an important quality control task in a rebar operation. Nonconformity attributed to missing or mislocated rebars adversely affects structural performance and construct-ability. Rebar craftsmen normally read two-dimensional (2D) shop drawings and install rebars after converting 2D objects to three-dimensional objects in a cognitive image. To ensure conformity, the installation is inspected manually, hence, being tedious and ...

Conformity between macro-mechanics and microscopic functions of hydrogen in failure is reviewed in reference to some models of hydrogen embrittlement (HE), focusing on the role of plasticity. Plastic strain localization, a characteristic feature of HE, is consistent with the hydrogen-enhanced creation of vacancies during plastic deformation. Constitutive relations that take into account the presence of voids describe well the ductile fracture process in HE. The effect of hydrogen on increasing the ...
