Precracks were inserted into the sample by sliding a fresh steel razor blade for every sample in the root of the machined notch to achieve a tip radius of [less than or equal to] 20 [micro]m and to achieve a total crack length
, a, to width, W, ratio of 0.
The stress intensity factor along the crack length
alpha] is crack length
(urn); [beta] is reliability index; G(Xj) is the limit state function; [K.
The present theoretical study focuses on stress intensity factor in RC beam with double incline notches to determine the critical crack length
and the fracture toughness in a shear crack.
The stress or strain life approach is called safe life design; crack length
approach is called damage tolerant design.
In the figures, the stress intensity factor solutions are plotted along the crack length
where 0 is located at the mid-section of the weld.
The measurement of the crack length
was repeated 3 times to get the average length.
It can also be used for automatic determination of crack length
and for full-field Digital Image Correlation (DIC).
The total surface area of cracks would be the total crack length
multiplied by the coating thickness.
IC] as a parameter of fracture toughness of material (indicating the initiation of crack) is a function of applied load, boundary conditions, crack length
, and structural geometry .
a, h, B, W, and P are the initial crack length
, interlayer thickness, specimen thickness, specimen width and applied load respectively.
Furthermore, the inspection system fully on LabView needs can be controlled to use custom test programs using the crack length
measuring device DCM-2 of MATELECT can.
