tensile testing

Sheet metal forming operations consist of simple bending, to stretching to deep drawing of complex parts. The mechanical properties of the sheet material greatly influence its formability, which is a measure of the amount of deformation the material can withstand prior to fracture. This blog post covers important definitions determining sheet metal characteristics, the test methods, and the equipment used to quantify them.

Dear all,

Choosing the most appropriate tensile grips to effectively secure your samples is critical in getting accurate measurements of tensile properties such as tensile strength, peak load, elongation, tensile modulus, and yield.

Materials Testing is that part of engineering design, development and research that relies on laboratory testing of one kind or another to answer questions. Testing is also required during manufacturing to ensure a material or product meets some predefined specification. A universal testing machine is used to measure the mechanical properties of materials intension, compression, bending or torsion. Common properties of interest include Offset Yield Strength, Young’s Modulus, Poisson's Ratio, Tensile and Compression Strength and Total Elongation.

How to perform a micro-tensile test without mechanically interacting with the test specimen? By using only optical methods!

I am new user of abaqus. I want to study the effect of cross head velocity and different strain rate on  flow stresses developed in a material. Based on leterature survey, many people used abaqus for this purpose. I created rectugular ASTM specimen in abaqus and while applying boundry condition i fixed one end all DOF and another end i want to give displacement witgh repect to time or constant linear velocity. So how to give dispacment with respect to time or constant linear velocity boundry condition.
