A numerical study of elastic bodies that are described by constitutive equations that exhibit limited strains

small strain
Implicit elasticity
Nonlinear finite elements
Unbounded stress

Recently, a very general and novel class of implicit bodies has been developed to describe the elastic response of solids. It contains as a special subclass the classical Cauchy and Green elastic bodies. Within the class of such bodies, one can obtain through a rigorous approximation, constitutive relations for the linearized strain as a nonlinear function of the stress. Such an approximation is not possible within classical theories of Cauchy and Green elasticity, where the process of linearization will only lead to the classical linearized elastic body.

Abstract

In this paper, we implement the radial basis functions for solving a classical type of time-fractional telegraph equation defined by Caputo sense for (1<α≤2). The presented method which is coupled of the radial basis functions and finite difference scheme achieves the semi-discrete solution. We investigate the stability, convergence and theoretical analysis of the scheme which verify the validity of the proposed method. Numerical results show the simplicity and accuracy of the presented method.

Paper "A new generalized Drucker–Prager flow rule for concrete under compression" published

Submitted by Jinqing Bao on
research

This paper is on my work at Singapore. I think this paper has the following contributions

(1) A concise flow rule is proposed for concrete, every item in the flow rule has clear physical meaning

(2) Let us know that for any material, the flow rule can be simple, and we don't have to pay attention to the potential funcion.

(3) When we propose a plastity constitutive law, we don't have to rely on commercial software like 

Abaqus any more, as a numreical calibration method is introduced.

Scanning AC nanocalorimetry study of Zr/B reactive multilayers

ultra high temperature ceramic

The reaction of Zr/B multilayers with a 50 nm modulation period has been studied using scanning AC nanocalorimetry at a heating rate of approximately 1,000 K/s. We describe a data reduction algorithm to determine the rate of heat released from the multilayer. Two different exothermic peaks are identified in the nanocalorimetry signal: a shallow peak at low temperature (200 - 650°C) and a sharp peak at elevated temperature (650 - 800°C).
