An isoparametric two-dimensional joint element with independent non-linear behavior models for normal and shear stress has been used to study different failure criteria and the accuracy of calculations. Testing of the behavior models indicated similar results obtained by other researchers with different finite element codes. JRTEMP is the first finite element program which can couple joint elements and thermal loading in plane stress, in plane strain and in axisymmetric cases. Joint normal stress behavior followed Goodman's (1976) hyperbolic law for normal stress-deformation relationship and shear behavior by Barton's (1977) peak shear strength criterion which is a function of normal stress. The examples of the study indicate that by applying non-linear model to the behavior of a joint, at least three integration points should be used.
