The picture above shows the experimental setup. A tensile test machine with an extensometer attached on the backside of the sample was used for measuring the conventional engineering strain-stress
Therefore, the tensile testing of pristine and notched 2D materials would advance the understanding of mechanics of 2D materials. Unlike the wet transfer that can be used to prepare samples for nanoindentation tests, dry transfer techniques have to be applied to load 2D materials over the testing area of micromechanical devices, regarding that . In summary, by developing robust sample transfer, shaping and clamping techniques, in situ quantitative tensile test of free-standing single-crystalline graphene monolayers has been successfully . It is also found that the developed material model describes the uniaxial tensile test curves better than Yld2000-2d yield function. The deep drawing test for 5754O aluminum alloy sheet was carried out and was simulated with different material models. The comparison between the experimental and simulation results indicates that the developed .
10.3.2 Tensile Test with Optical 2D DIC. The tensile test is then set-up on a 25 kN Tinius Olsen electric machine, using a pair of wedge-type grips to hold the flat tensile specimen. For this experiment, the tensile test set-up is equipped with an optical 2D digital image correlation, where the strain measurements will be later used to be .2 The tutorial contains screenshots to aid the model development. Every step is highlighted with red numbering. Let’s start a new model in ABAQUS and save it as “SimpleTension.cae”.Open the Part module and click on the Create Part icon. Set the modeling space to 2D Planar and leave the base feature on Shell. Set the approximate size to 5 and finally click Continue (see Figure 2 for .The testing device records the deformation of the specimen as well as the force required using the crosshead or an extensometer. Then, the tensile stress and strain are computed by relating the read values to the dimensions of the .

Accurate measurements of tensile mechanical properties are very important for the engineering design and the safety analysis of materials. Among the testing methods for the mechanical properties of materials, the uniaxial tensile test is considered to be the most efficient method as it is the most favorable way to measure the tensile and fatigue properties and .
Clearly, stress and strain are related. Stress and strain are related by a constitutive law, and we can determine their relationship experimentally by measuring how much stress is required to stretch a material.This measurement can be done using a tensile test. In the simplest case, the more you pull on an object, the more it deforms, and for small values of strain this relationship . There are numerous studies focused on the tensile properties of different materials using the DIC method. For example, Cerbu et al. applied the DIC method to determine the Poisson’s ratio on aluminium alloy and composite materials under the tensile test [15].The experimental approach based on the DIC method was successfully used to predict the uniaxial .
