Tensile Test for Steel Material with High-Accuracy Strain Control

Universal Tensile Testing Machine

Here we used the Shimadzu Autograph AG-50kNX precision universal testing machine with the SSG-50-10H extensometer to perform tensile testing of an SPCC steel sheet sample according to 2 types of strain increase rate control as specified in the proposed ISO 6892 revision, in order to verify the results and load rate control accuracy.

Tensile Test of High Tensile Strength Steel

Universal Tensile Testing Machine

There is a deeply rooted need for tensile strength tests for extremely thin copper foil used for printed circuits and packaging materials in electronic and food industry. Practical tests, however, are often confronted with the problem of getting reliable data due to fluctuations and breakage of the specimen at the gripped portion. Consequently, static tensile tests of extremely thin foils as thin as 0.02mm must be conduced in a manner different from general tests. The following is an introduction of testing methods for highly reliable test results and some ideas on grip that encourage normal breakage of the specimen.

Static Tensile Test of Small Pipe Selection of Optimal Grips and Extensometers (II)

Universal Tensile Testing Machine

The mechanical properties of aluminum and copper pipes, often used in air conditioners and in various precision instruments, must be evaluated in the form of their actual use. Static tests are conducted with both ends of the pipe specimen processed flat and the center portion remaining in the form of a pipe, while conventional testing methods are performed by inserting a core into the gripped part of the specimen to prevent crushing. Actual test conditions and test results are introduced here.

Observations of Turbine Defects (X-ray CT)

inspeXio SMX-225CTX-Ray Computed Tomography System

X-ray fluoroscopy systems offer non-destructive observations of the internal structures of objects. They are effective instruments for identifying the cause of failure of industrial products. By simplifying the non-destructive tomographic imaging and 3D imaging of the interior of objects, observations of internal shapes, dimensional measurements, and density observations, these systems provide a powerful tool for defect analysis and quality control.

Automatic Elongation and Width Measurements In Tensile Tests of Thin Steel Plates

Universal Tensile Testing Machine

Simply attach an automatic extensometer and width sensor to the Autograph precision universal tester to automate the measurement of various physical properties, including r-values, which are useful in evaluating the workability of steel plates. This enables easily performing tests that conventionally used manual extensometers and width sensors, or strain gauges.

Evaluation of Functioning of Shape Memory Alloys in Automatic Stress-Strain Control Mode of Shimadzu Autograph

Universal Tensile Testing Machine

Shape memory alloys, drawing keen interest for their unique characteristics as metallic materials, are currently used widely in the fields of space exploration, the automobile industry, electronic instruments, medical instruments, and consumer goods. Further study to expand their application is going on. Change of shape, recovery ratio and recovery force are major factors of the shape memory effect. One area of inquiry of particular interest is how the change of stress and strain is influenced by temperature. The Shimadzu Autograph, an automatic stress-strain control device, can control loading rate and gauge length strain rate through its computer control system.

Evaluation of Press Work on Sheet Metal

Universal Tensile Testing Machine

Pressed parts made of lightweight materials with poor workability, such as high tensile steel, aluminum alloys, and magnesium alloys, are essential for reducing the weight of transportation equipment. Repeatedly modifying the die to achieve a target shape not only increases costs, but also lengthens the development period. One solution currently being tried is to reduce the number of actual samples evaluated by using simulation to predict forming problems in advance. As simulation technology continues to evolve, the use of methods such as the Yoshida-Uemori Model, which considers a greater number of factors than previous methods, including plastic strain dependence of elasticity based on the r-value and the Bauschinger effect, has increased.

Evaluation of the Bauschinger Effect on a Steel Sheet Specimen Subjected to In-plane Reverse Loading Test

Universal Tensile Testing Machine

In dies manufacturing for presses, the spring-back phenomenon is an issue causing forming failures that need to be coped with by trial and error, which requires tremendous time and costs. In recent years, on the other hand, computer aided engineering (CAE) analytical technologies are utilized in various fields to simulate product designs on a computer for reducing the number of times and costs of trial production. Regarding dies manufacturing for presses, simulation is also coming to be used to predict the springback phenomenon in die design as an effective tool to achieve drastic cost reductions. This article presents an example of evaluating the Bauschinger effect on a 1 mm thick cold rolled steel sheet (SPCC) without buckling the sheet, using a Bauschinger effect measuring fixture.
