Development of Quadratic Triangular (T6) Elements in Java
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
This study developed Quadratic Triangular (T6) elements using an object oriented approach and the Java programming language. A review of the work of Kansara (2004) and Nikishkov (2010) was conducted to develop a finite element program which addresses the deficiencies of Constant Strain Triangle (CST) elements developed by Kansara (2004). The program computes displacements and stresses at each node of the finite element model. Several test examples were analyzed using the program and results were compared with those obtained from Kansara (2004), the commercial finite element analysis program SAP 2000 and LISA respectively. The results obtained from the analysis of the example problems were found to be very accurate when compared to those obtained from Kansara (2004), SAP 2000 and LISA. The difference in displacements and stresses computed by the two programs was very negligible.
