Study on cyclic loading and unloading characteristics of remolded saturated soft soil [PDF]

Vibroengineering Procedia, 2020
This paper described a continuous load one-dimensional K0 consolidation apparatus developed and improved, conducted an axial cyclic loading and unloading test of saturated soft clay. It can be known from the experimental comparison that during the unloading period, a stress strain curve of saturated soft clay is made hyperbolic.

Orthotropic cyclic stress-softening model for pure shear during repeated loading and unloading [PDF]

, 2014
We derive an orthotropic model to describe the cyclic stress softening of a carbon-filled rubber vulcanizate through multiple stress-strain cycles with increasing values of the maximum strain. We specialize the deformation to pure shear loading.

Constitutive modeling of the anisotropic behavior of Mullins softened filled rubbers [PDF]

, 2003
Original constitutive modeling is proposed for filled rubber materials in order to capture the anisotropic softened behavior induced by general non-proportional pre-loading histo-ries.

Experimental Study on Coal Specimens Subjected to Uniaxial Cyclic Loading and Unloading

Applied Sciences, 2022
The paper represents a test investigation of the mechanical properties and acoustic emission (AE) characteristics of low-strength coal specimens subjected to cyclic loading and unloading. From the lab tests, the following conclusions can be obtained: (1) The axial strain is very well linear with the loading–unloading cycle number, and the ...

Analysis of permeability evolution law of gas-bearing coal under cyclic loading condition

Meitan kexue jishu
In order to explore the permeability evolution law of gas-bearing coal under different cyclic loading and unloading conditions, raw coal samples were taken as the research object, and cyclic loading-unloading experiments of gas-bearing coal were designed

Nonlinear Model for Reinforced Concrete under Cyclic Loading

, 2005
Most of the available shear models for reinforced concrete rely on empirical formulations. In this study, a rational shear stress function is used to define the shear stress–strain envelope for reinforced concrete. Cyclic rules are proposed to define the

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]

, 2012
The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and
