New tension-compression damage model for complex analysis of concrete structures [PDF]
, 2016 A new damage model, based on continuum damage mechanics and simulating the opening, closing, and reopening of cracks in concrete using only one surface of discontinuity, is proposed in this article.

A computer-controlled four-roll mill for investigations of particle and drop dynamics in two-dimensional linear shear flows [PDF]
, 1986 In this paper we describe the design and operating characteristics of a computer-controlled four-roll mill for investigations of particle and drop dynamics in two-dimensional linear flows.

Modelling strong seismic ground motion: three-dimensional loading path versus wavefield polarization [PDF]
, 2012 Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil.

Nonlinear Shear Waves in Compressible Media: Occurrence of Strong Shocks
MathematicsApparently for the first time, shear shock wave fronts (shear shocks) are observed in a hyperfoam at the propagation of shear waves. The hyperfoam is modelled by the Ogden compressible hyperelastic potential. A possible appearance of the shear shocks may

Solid-fluid dynamics of yield-stress fluids
, 2014 On the example of two-phase continua experiencing stress induced solid-fluid phase transitions we explore the use of the Euler structure in the formulation of the governing equations.

Soils and Foundations, 2022 The structure of the sedimentary clay influences its mechanical behavior in non-negligible ways. This paper proposes an effective approach for investigating the in-situ stiffness characteristics from shear modulus and strain decay curves (G–γ curves ...

A quasi-3D hyperbolic shear deformation theory for functionally graded plates [PDF]
, 2013 A quasi-3D hyperbolic shear deformation theory for functionally graded plates is developed. The theory accounts for both shear deformation and thickness-stretching effects by a hyperbolic variation of all displacements across the thickness, and satisfies

Do Finite-Size Lyapunov Exponents Detect Coherent Structures? [PDF]
, 2013 Ridges of the Finite-Size Lyapunov Exponent (FSLE) field have been used as indicators of hyperbolic Lagrangian Coherent Structures (LCSs). A rigorous mathematical link between the FSLE and LCSs, however, has been missing. Here we prove that an FSLE ridge
