... and DC-CC-FFT algorithms are proposed. The DC-FFT S algorithm is a modified discrete convolution and fast Fourier transform algorithm with superposition of influence coefficients. The DC-CC-FFT algorithm is a hybrid fast Fourier transform based algorithm, which combines the discrete convolution–FFT...

... on an integral formulation or semi-analytical method. The application of both the conjugate gradient method and the discrete convolution and fast Fourier transform technique allows keeping the computing time reasonable when performing transient 3D simulations while solving the contact problem and calculating...

... of lubrication conditions, and that the solution methods are computationally efficient and robust. It can be found by checking carefully the calculation process that Eq. ( 13 ) is in fact a discrete two-dimensional linear convolution. In order to use the FFT technique in the calculation of surface...

... with regularly distributed heat. In this work, irregularly distributed frictional heat is applied on the surface of a moving body. Temperature and surface normal thermoelastic displacement are solved by using an efficient numerical procedure involving the discrete convolution and fast Fourier transform algorithm...
