A modelling technique for calculating stress intensity factors for structures reinforced by bonded straps. Part I: Mechanisms and formulation [PDF]
, 2010 This paper describes a 2D FE modelling technique for predicting fatigue crack growth life of integral structures reinforced by bonded straps. This kind of design offers a solution to the intrinsic lack of damage tolerance of integral structures.

EFFECT OF PRESTRESSED FORCE AND SIZE OF REINFORCEMENT ON CORROSION CRACK WIDTH IN CONCRETE MEMBER [PDF]
Journal of Engineering Science and Technology, 2017 One of the main factors which terminate service life of concrete structure in corrosive environment is corrosion attack. Rust expansion of corroded reinforcement in concrete causes corrosion crack.

Evaluation of the intrinsic crack growth rates of weld joints [PDF]
, 2011 A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

Using 3D-Printed Formwork to Enable Controlled Crack Creation in Concrete Specimens
CivilEngThe employment of automated non-destructive testing (NDT) methods for crack characterization in concrete, needs calibration and benchmarking in a controlled environment. This requires test specimen with comparable and ideally reproducible cracks. To this

A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]
, 2011 Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.
