In the paper, new hybrid (numerical-analytical) methods to calculate the J-integral, the CTOD, and the load line displacement are presented. The proposed solutions are based on FEM calculations which were done for SEN(B) specimens dominated by plane strain condition. The paper includes the verification of the existing limit load solution for SEN(B) specimen with proposal of the new analytical formulae,...
In the paper, the verification of the limit load solutions proposed by EPRI procedures for single edge notched plate under tension (SEN(T)) is presented. For the concept of limit load of the component containing a crack, the force (or torque or pressure) which causes a full plasticity of the uncracked ligament of the structural component must be understood. It should be noted that the value of the...
W pracy przeprowadzono analizę wpływu modelu MES na wartość naprężeń przed frontem pęknięcia w materiałach sprężysto-plastycznych oraz wyznaczaną w sposób numeryczny wartość całki J. Obliczenia prowadzono dla płaskiego stanu odkształcenia przy założeniu dużych odkształceń.
