Dynamic mechanical properties (BMP) refer to the mechanical properties of a polymeric material, such as a composite, when a periodic load imposes a strain (deformation) on the material. Dynamic mechanical analysis (DMA) is used to determine low cycle fatigue, high cycle fatigue, and... [Pg.41]

When constant stress (5) amplitudes are encountered, the process is known as high cycle fatigue, because failure generally occurs only when N exceeds 10 cycles. Data from high cycle fatigue tests are reported in the form of an 5 vs Ai curve, as shown in Figure 4b (7). [Pg.113]

High temperature materials which exhibit the greatest resistance to high cycle fatigue on a strength basis, ie, fatigue limit/tensile strength vs are... [Pg.113]

In the case of a cracked component a crack analysis should be run to verify that the crack is a high cycle fatigue failure. An instrumented operational test of the component will identify the frequencies of high vibration levels causing the problem. [Pg.347]

Nowadays the importance of contact and surface problems in many technological fields is well understood. They are complex and inherently non-linear due to the moving boundary and the different properties of materials, particularly along the contact surfaces. Structural components fail by wear, corrosion, high cycle fatigue etc, that is to say they are affected by surface conditions. The use of surface treatments can reduce the cost of components and extend the life of the elements for surfaces undergoing contact, a problem that is specifically addressed by the Conference.
