The formability analysis of an aluminum-based alloy 8011 sheet is carried in this work. Erichsen test is carried out and they are simulated by the axisymmetric finite element method. The effects of sheet thickness and frictional condition between the punch and sheet on formability is predicted and compared with the experimental results of the Erich...

A large-scale shear apparatus has been originally developed and built to test the mechanical properties of coarse-grained material. It was used to evaluate the shear behaviour of brash ice. The brash ice blocks were collected at Luleå harbour in two separate measuring campaigns in March 2020 and March 2021. The shear cylinder was loaded with brash...
Third generation artificial turf systems are comprised of a range of polymeric and elastomeric materials that exhibit non-linear and strain rate dependent behaviours under the complex loads applied from players and equipment. An elastomeric shockpad is often included beneath the carpet layer to aid in the absorption of impact forces. The purpose of...
Microstructures on polymer surfaces are known to reduce friction and the visibility of scratches. Due to the complex interaction of multiple surface areas in contact with each other the prediction of coefficient of friction (COF) or wear is difficult and depends on an empirical solution. This article deals with possibilities of calculating the defo...
A new hyperelastic membrane material model is proposed for single layer blue phosphorus ($\beta\text{-P}$), also known as blue phosphorene. The model is fully nonlinear and captures the anisotropy of $\beta\text{-P}$ at large strains. The material model is calibrated from density functional theory (DFT) calculations considering a set of elementary...
One of trends in the ATF fuel design is to add a secondary phase with high thermal conductivity and low neutron absorption into the UO 2 fuel matrix. In this work, the SiC is selected as an additive since its behaviour under neutron irradiation is well understood. For the assessment of SiC influence on the fuel performance during burnup, the FEMAXI...

... Cavitation was observed to be lower in equi-biaxial disfigurement than in near plane-strain forming attributable to the lower hydrostatic pressure. Using the finite element method, V.P. Srinivasan et al [3] investigated the formability of 8011 aluminium series alloy. Using axisymmetric finite element technique, the Erichsen cup test is successfully conducted. ...
Sheet metal forming a critical manufacturing process in automotive, aeronautic, and industrial sectors. Due to their attractive quality and light weight in comparison with all other alloys, aluminium-based alloy sheets have overtaken other alloys in some applications. Formability refers to the ability of sheet metals to be formed into various shapes without fracture. The formability of sheet is determined by the material’s properties, forming variables, sheet width. The use of orthogonal arrays in Taguchi experiments allows the effects of multiple parameters to be studied efficiently. In this manuscript, the forming limit diagram for Al 8011 sheets of 1 mm and 1.2 mm thickness was evaluated using a Taguchi orthogonal array at 150°C and 450°C. These specimens are cut in two different directions (0° and 90°) to the rolling direction, and experiments are undertaken out at a strain rate of 0.001/s ⁻¹. It has been observed that specimens from the transverse direction is one of the strongest. The formability characteristics of Al 8011 alloy sheet have been observed to change with temperature and thickness using FLD. The fracture micrographs are studied using scanning electron microscopy. The comparative analysis of these data showed that the material’s formability has dramatically increased.
... As seen by the findings of the study, welding speed plays a virtual role in changing tensile strength [1].Lee et al. [6] observed, in their experiments on FSW of cast aluminium alloy A356 to wrought Aluminium alloy AA6061, that the stir zone consisted mainly of the material put on the retreating side. Uniaxial strain studies by Srinivasan et al. [7] learned increasing sheet thickness from this research, that using lubrication means improved formability. The effects of tool shoulder and probe geometries on friction stirred Aluminium welds were investigated by Mohanty et al. [8] with respect to weld strength, weld cross-section area, weld grain size and thermo-mechanically influenced zone grain size using response surface methodology. ...
Aluminium alloy 6061-T6 and Stainless ASS 304 are used in present study. The friction stir welding is used in this process to join the base metals. The uniaxial tensile testing procedure parameters, Orientation, Temperature, Strain rate suppose a key job in better Yield strength and % of elongation. The temperature (27 °C, 350 °C, 500 °C), Orientation (R0, R45, R90) to the rolling direction, strain rate (0.1, 0.01, 0.001) S⁻¹ were taken. The L9 orthogonal Taguchi method was utilized to know the impact of procedure parameter on each factor.
Aluminum alloys are making a special consideration for extreme temperature applications in service background of aircraft structures, missile engines, and pressure containers. This creates crucial to recognize various mechanical properties of the Al 8011 alloy such as yield strength (ys), % of elongate and ultimate strength (uts) have been valued by depleting uniaxial tensile loads. The mechanical properties of aluminum alloy materials are purely reliant on the rate at which the part is heated and quenched. The tensile experiments are accompanied at 150 °C and 450 °C with different strain conditions (0.1 s⁻¹, 0.001 s⁻¹) to find the material behavior of Al 8011 alloy sheet. The Taguchi orthogonal array and the (S/N) signal to noise ratio are used to analyze the effect of elected process considerations and their levels.
