Zusammenfassung:This paper deals with solving Poisson's equation with conditions on Dirichlet's limits in an isosceles trapezium with two cracks. The large singular finite elements method used gives satisfactory results in all the domain of study. Numerical values obtained are very accurate for the constraint function and its first derivatives except at the ends of cracks where major changes were registered.
