In the case of dynamic loads, the material fatigue must also be taken into account.

His main area of expertise was the study of material fatigue.

The cause of the crash was material fatigue.

Also, detailed examination of the surface of the broken disc showed significant evidence of material fatigue.

Material fatigue inducing cracks in moving structures.

CR-39 is also resistant to most solvents and other chemicals, gamma radiation, aging, and to material fatigue.

The process of material fatigue is thus governed largely by the shape of the excitation profile and the response it produces.

He has published over 100 journal papers with a focus on non linear fracture mechanics, material fatigue, and the associated computational methods.

Initially, this works quite well, because the elasticity of the material is still sufficient, but material fatigue can set in and cause permanent deformations.

In 1987 cracks required major repair works, and in 2006 further cracks and signs of material fatigue were found.

Neuber's rule and the Hoffmann-Seeger method are available for elastoplastic material fatigue computations.

Vibration fatigue is a mechanical engineering term describing material fatigue, caused by forced vibration of random nature.

Another major concern, though of non-corrosive kind, is material fatigue caused by cyclical heating and cooling and associated thermal expansion mechanical stresses.

Thermal expansion produces mechanical stresses that may cause material fatigue, especially when the thermal expansion coefficients of the materials are different.

More likely, today's cameras will be short-lived not because of materials fatigue or electronic failures, but because the rate of technological change has increased so drastically.

The cause of the damage has not been published by STX, but design or construction flaws, material fatigue and incorrect loading have all been suspected.

Their high elastic modulus is favorable for absorbing vibrations and lowering material fatigue of attached modules and wire bonds.

"In actuality," Spock said, "the cause might have been simply material fatigue, possibly brought about by a weakening of the manifold during our battle with the Klingons."

Surface fatigue is a process by which the surface of a material is weakened by cyclic loading, which is one type of general material fatigue.

When the East Germans requested data to calculate certain actions of the system or to judge material fatigue, Moscow might give a limited answer or none at all, the experts said.

This became a tragic, textbook example of stress concentration increase of a "stepped shaft", which in-turn initiated the formation of micro-cracks through the material core, a phenomenon known as material fatigue.

Litz wire is one kind of stranded wire, but, in this case, the reason for its use is not the usual one of avoiding complete wire breakage due to material fatigue.

In materials science and material fatigue, a crack arrestor or rip-stop doubler is a structurally strong ring or strip of material which serves to contain stress cracking that could lead to catastrophic failure of a device.

When thrust was applied, the low pressure turbine disc in engine number 2 disintegrated because of material fatigue; parts of the disc damaged engines number 1 and 3 and severed control pushers for both horizontal and vertical stabilizers.

The controls must also be carried out in such a way that the inspector does not just go on board and check whether there are any fire extinguishers missing, rather there must be materials testing, for this ship obviously broke up on account of material fatigue.
