“…Interface debonding refers to delamination at the interface and crack propagation along the interface. 24 Here, interfacial debonding of specimens is observed at 30 times under an optical microscope, and similar trends can be seen from the results of Type-A and Type-B tests.…”

In this paper, the effects of maximum load, load ratio, and average load on fatigue crack propagation of Zr702/TA2/Q345R composite plate with a crack normal to the interface are studied by experiment and finite element method. When crack propagates to the interface from the compliant material side, the crack growth rate decreases to the minimum at first. After crack penetrates through the interface, the fatigue crack growth rate accelerates continuously. When crack propagates to the interface from the stiff material side, the fatigue crack growth rate generally increases with the crack length. Regardless of the direction of crack growth, the increase of load ratio will weaken the difference of crack growth rate near the interface caused by material property mismatch. Finite element results show that elastic modulus mismatch significantly changes the variation of the stress intensity factor amplitude. All results demonstrate that crack growth rate is dependent on the competition of the stress intensity factor amplitude, the fatigue crack growth rate in the corresponding material, and the interface strength.

“…Nowadays, up to 65% of the mechanisms of transport means elements are known to get out of order under the influence of aggressive (corrosive) environment and mechanical stresses; up to 25% of these mechanisms are broken down due to the overloads caused by strength losses because of corrosion damages [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. According to the data on agrarian production development in Ukraine, the growth of the transportation volumes of chemical and mineral fertilizers [15] is about 2% of all cargoes.…”

“…To calculate the durability of thin-walled vehicle elements, it is necessary to consider the influence of aggressive working environment on the corrosion-fatigue destruction [1,7,9,10,11]. Delayed spontaneous fracture of structural elements under the action of variable in time (cyclic) loads and corrosive-aggressive environments is relatively continuous but dangerous process because of the low degree of its predictability and diagnosis.…”

The approach for determining the residual life of the vehicles’ thin-walled metal elements with cracks under the action of cyclic loads and corrosive environment is developed based on the first law of thermodynamics and the fracture mechanics principles. Based on the results of the mathematical description of electrochemical reactions and separate data of fracture mechanics, the equation describing the kinetics of the corrosion-fatigue cracks propagation is deduced. This equation and the initial and final conditions are a mathematical model for determining the residual life of structural elements. The correctness of the developed analytical models is confirmed by the experimental data known in the literature. The performance of this model is demonstrated on the example of determining the residual life of a plate made of 17G1S steel. The plate was diluted by a crack in a 3% NaCl solution and subjected to cyclic loading. An increase in the initial size of corrosion-fatigue cracks is significant to reduce the period of their subcritical growth.

Bu çalışmada, 1,5 mm kalınlığa sahip TRIP 800 çelik plakaları bakır esaslı S Cu 6100 (CuAl8) teliyle gaz metal ark lehimleme yöntemiyle birleştirilmiştir. Numuneler, bindirme birleştirme formunda hazırlanmıştır. Koruyucu gaz olarak argon kullanılmıştır ve lehimleme işlemleri 8, 10, 12, 14 ve 16 L/dk koruyucu gaz çıkış hızında yapılmıştır. Birleştirme noktalarının çekme dayanımı belirlenmiştir ve TRIP 800 çeliğinin gaz metal ark lehimleme tekniğiyle farklı koruyucu gaz çıkış hızlarında birleşebilirliğini görmek için birleştirme noktalarının mikro ve makroyapıları optik mikroskopta incelenmiştir.
