Indentation of a rigid sphere into an elastic substrate with surface tension and adhesionProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences - Tập 471 Số 2175 - Trang 20140727 - 2015

The surface tension of compliant materials such as gels provides resistance to deformation in addition to and sometimes surpassing that owing to elasticity. This paper studies how surface tension changes the contact mechanics of a small hard sphere indenting a soft elastic substrate. Previous studies have examined the special case where the external load is zero, so contact is...... hiện toàn bộ
On analyticity of travelling water wavesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences - Tập 461 Số 2057 - Trang 1283-1309 - 2005
David P. Nicholls, Fernando Reitich
In this paper we establish the existence and analyticity of periodic solutions of a classical free-boundary model of the evolution of three-dimensional, capillary–gravity waves on the surface of an ideal fluid. The result is achieved through the application of bifurcation theory to a boundary perturbation formulation of the problem, and it yields analyticity

Non-reciprocal wave propagation in modulated elastic metamaterialsProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences - Tập 473 Số 2202 - Trang 20170188 - 2017

Time-reversal symmetry for elastic wave propagation breaks down in a resonant mass-in-mass lattice whose inner-stiffness is weakly modulated in space and in time in a wave-like fashion. Specifically, one-way wave transmission, conversion and amplification as well as unidirectional wave blocking are demonstrated analytically through an asymptotic analysis based on coupled mode theory and nu...... hiện toàn bộ
A theorem on the existence of trace-form generalized entropiesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences - Tập 471 Số 2183 - Trang 20150165 - 2015
Piergiulio Tempesta
An analytic technique is proposed, which allows to generate many new examples of entropic functionals generalizing the standard Boltzmann–Gibbs entropy. Our approach is based on the existence of a group-theoretical structure, which is intimately related with the notion of entropy, as clarified in recent work of the author. The new entropies proposed satisfy the first three Shannon–Khinchin...... hiện toàn bộ
A depth-averaged debris-flow model that includes the effects of evolving dilatancy. II. Numerical predictions and experimental testsProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences - Tập 470 Số 2170 - Trang 20130820 - 2014
David L. George, Richard M. Iverson
We evaluate a new depth-averaged mathematical model that is designed to simulate all stages of debris-flow motion, from initiation to deposition. A companion paper shows how the model's five governing equations describe simultaneous evolution of flow thickness, solid volume fraction, basal pore-fluid pressure and two components of flow momentum. Each equation contains a source term that re...... hiện toàn bộ
