Abstract Compression of paperboard is a common procedure during industrial package forming and better knowledge the material response needed to avoid defective packages waste. To go beyond current modelling approaches, experimental identification mechanisms underlying macroscopic stress–strain responses needed. In this study, in-situ uniaxial compression studied through synchrotron tomography a...

Article history: Received 2 January 2015 Received in revised form 22 October 2015 Accepted 23 October 2015 Available online 27 October 2015 The hot deformation behaviour of Inconel alloy IN718 was studied in the temperature range of 950–1100 °C and at strain rates of 0.01 and 1 s with a view to understand the microstructural evolution as a function of strain rate and temperature. For this purpo...

Many factors such as production methods and structural parameters have distinctive influence on the quality and performance of a hand woven carpet. To investigate the effects of some variables, eighteen samples of carpet vary, in knot density, pile height and percentage of slipe wool, were manufactured. Pile yarn performance was assessed by using load-displacement compression curve, obtained fr...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...

With the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. In this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of AZ31B. Due to asymmetric and anisotropic behav...

Many water-related problems are confronted in coal mining, and the mechanical properties of inevitably deteriorate due to water–rock interactions. Therefore, it is necessary study macroscopic damage constitutive model water-bearing for safe mining. The uniaxial compression tests raw samples with five moisture contents under four loading rates were carried out. Based on test, Drucker–Prager crit...

The hot deformation and dynamic recrystallization behavior of the dual-phase Mg-9Li-3Al-2Sr-2Y alloy had been investigated using a compression test. The typical dual-phase structure was observed, and average of grain size of as-homogenized alloy is about 110 µm. It mainly contains β-Li, α-Mg, Al₄Sr and Al₂Y phases. The dynamic recrystallization (DRX) kinetic was established based on an Avrami t...

The stress–strain response of a Fe–17.5Mn–0.7C–2Al TWIP steel during cyclic loading has been investigated by means of tension–compression tests within the strain limits of 72%, 75% and 710%. In addition, the microstructural evolution during the 75% cyclic test has also been studied. The difference between the forward and reverse stress for each pre-strain has been analyzed at 0.2% offset strain...

A hardening response is often observed for shear-dominated large deformation of Carbon Fibre Reinforced Plastics (CFRP). This non-linear modelled by fitting a strain law against experimental stress-strain curves. Inspired crystal plasticity framework, phenomenological model developed to capture matrix shearing and fibre rotation CFRP under finite strain. first verified simple shear transverse c...

Researchers have conducted finite element (FE) analyses with human models to predict injuries due to traffic accidents or falling. In most of their analyses, cortical bone was simply modeled as a general isotropic elastoplastic material. In this study, a constitutive model of cortical bone considering anisotropic inelasticity and damage evolution was developed to predict injuries more accuratel...
