Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.

The Westergaard method of crack analysis is closely related to the complex variable method of Kolosov- Muskhelishvili we discussed in class. In this approach, crack problems can be solved using only one complex potential function Z(z), where = Re Z-y Im Z % = ReZ+yIm Z 33 o = -y Re Z XV The potential function for equal and opposite point loads on a crack is: P √a²-b² π (z-b)√√₂²-a² Z(z): Derive the stress intensity factor at the left and right crack tips for this configuration. a жа y Log P a
Create a 2D contour plot to allow the performance of the structure to be assessed against the maximum distortion energy (von Mises) criteria. Comment on the results. You can do this by plotting a contour of the von-mises stress and then normalising the result against the yield stress. This will produce a contour plot of the failure index. This index represents the ratio of the von-mises stress to the yield stress of the material.
