Boundary Element Method in Photoelasticity as a Separation Method 

Atilla ÖZÜTOK, Ahmet Yalçın AKÖZ

Abstract


Principal Stress direction and their difference can be obtained directly by the photoelastic 
experiments using the isoclonic and isochromatic fringe patterns respectively. To obtain the individual 
principal stresses or the elements of the stress tensor, additional operation is required. The way for 
obtaining the elements of the stress tensor is called the separation method. In this study, the adaptation 
of the Boundary Integral Equation to photoelasticity is investigated as a separation technique that the 
stress distribution in a square plate which is loaded by concentrated forces on natural edges along 
symmetry axis is investigated.  


Keywords


Photoelasticity; Boundary element method; separation method.
