Analysis of high velocity impacts of quasibrittle material fragments with a Hopkinson bar [PDF]
EPJ Web of Conferences, 2021 In this work it has been characterized the impact behaviour of quasibrittle fragments against a Hopkinson bar in a wide range of impact velocities (70-180 m/s). Hopkinson bar is designed to measure the impact forces thanks to a proper instrumentation. In

Mechanics Analysis of Rough Surface Based on Shoulder-Shoulder Contact
Applied Sciences, 2021 Proper methods and models for mechanical analysis of rough surface can improve the theory of surface contact. When the topography parameters of two rough surfaces are similar, the contact should be considered shoulder-shoulder rather than top-top.

Mechanizing Nonstandard Real Analysis [PDF]
LMS Journal of Computation and Mathematics, 2000 AbstractThis paper first describes the construction and use of the hyperreals in the theorem-prover Isabelle within the framework of higher-order logic (HOL). The theory, which includes infinitesimals and infinite numbers, is based on the hyperreal number system developed by Abraham Robinson in his nonstandard analysis (NSA).

On Λ-Fractional Analysis and Mechanics [PDF]
Axioms, 2022 Λ-Fractional analysis was introduced to fill up the mathematical gap exhibited in fractional calculus, where the various fractional derivatives fail to fulfill the prerequisites demanded by differential topology. Nevertheless, the various advantages exhibited by the fractional derivatives, and especially their non-local character, attracted the ...
