“…Friction forces generated at the interfaces lead to the dissipation of energy of the vibrating blade system, see Zmitrowicz [97][98][99]. Special friction dampers mounted between turbine blades have been studied by Pfeiffer and Glocker [60] and Sextro [100].…”

Contact stresses are identified as normal and tangential forces between contacting solids. The normal stresses are modeled using unilateral and complementary conditions, elastic response and normal compliance. Friction laws describe the tangential traction. Friction of materials depends on pressure, sliding velocity, surface temperature, time of contact, surface roughness and presence of wear debris. Phenomenological, micromechanical and atomic-scale models as well as non-classical models of anisotropic and heterogeneous friction are important steps in the development of friction modeling. Sophisticated friction models are desirable in vibrating systems, materials processing, rolling contacts, rubber and polymers, geomechanics, bioengineering and living systems. Main numerical methods in contact mechanics are: finite element method, boundary element method and discrete element method. To include specific contact constraints, the following computing techniques are applied: Lagrange multipliers, penalty function, perturbated and augmented Lagrangian methods, mathematical programming methods. The advances of adhesion and impact modeling are outlined in this paper.

“…However, the shrouded rotor blade design will cause the blade mode shapes to be complex, and in some cases both bending and torsion mode components can be present at the same time in a single mode [6]. Unfortunately, most existing analyses deal with uncoupled simple mode shape models, which cannot be used for the combined bending and torsion system mode analysis, and judgment based on past experience and experiments must be used to determine the acceptability of a shrouded rotor blade design [7][8][9][10]. On the other hand, prediction of the forced response of shrouded disc assemblies is still a challenging engineering task because of unknown excitation loads and friction damping effects [11].…”

“…factors [1] such as the sliding speed [2][3][4], surface roughness [5][6][7][8][9][10][11][12], temperature [1,14], normal force [12,[15][16][17][18][19][20] and the dynamic interaction of the contacting bodies [21][22][23][24][25][26][27]. Precise modeling is possible when the above mentioned factors are considered.…”
