Damping Perturbation Based Time Integration Asymptotic Method for Structural Dynamics

Publicated to: International Journal of Computational Methods. 19 (10): 1-33 - 2022-01-01 19(10), DOI: 10.1142/S0219876222500220

Abstract

In this paper a novel time integration numerical method based on artificial perturbation of damping is proposed. Viscous dissipative terms in the structural dynamics equations of motion are perturbed by an artificial parameter. The subsequent asymptotic expansion of the transient response results in an infinite series which can be summed, leading to a well-defined new step-by-step explicit iterative scheme. Precise integration algorithms are designed for the construction of the main matrices. Conditions for convergence and numerical properties, i.e., stability and accuracy are also studied in detail. The proposed approach is validated with a numerical example, showing high accuracy with respect to other existing methods in literature.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-05:

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 2 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
