Stability of the DQ time integration scheme for the solution of second-order ODEs for different types of sampling time points On the other hand, unconditionally stable algorithms can be achieved...

... regions have been discussed and classified. Section 1 gives a few of the many applications of fractional calculus to physical problems. In Sec. 2 an equation that contains both integration and differentiation is presented using geometrical observations about the relationship between the changes...

...J. H. Chang; J. S. Lin A fracture parameter M c is proposed for evaluation of the surface energy associated with the creation of multiple curved cracks in 2D rubbery solids under the action of large deformation. Based on the concept of the M -integral, the parameter is developed by performing...

... reduces the number of unknowns to solve in the time-integration process and also favors the use of advanced ODE algorithms, enhancing the efficiency and robustness of time integration. The issue of the imposition of vorticity boundary conditions is addressed, and details of the implementation of the KLE...
