Material Testing

Textile Strength Testing

Textiles, yarn, thread, fabrics, wool, cotton, and other animal and plant-derived fibers are commonly tested to ensure product quality by assessing the performance of materials and making sure they are acceptable towards proper end-use. This blog post will cover certain mechanical testing methods to test fabric and go over the testing standards.

Full blog post, including the recommended equipment, can be found here.

Biomechanical Testing

Biomechanics & Biomechanical Testing

Full blog post can be found here

Key concepts for medical device design include biomechanics, biocompatibility, and biofunctionality. This post will go over the mechanics of an exemplar biological tissue, the bone, and mechanical testing of biomaterials that are used in developing medical devices and equipment.

Equipment for Bend Testing per ASTM Standards and User-Specific Applications

While it is easy to imagine why bend testing needs to be performed on rigid materials like plastics (ASTM D790) and concrete (ASTM C1609), in reality bend test applications are common in a variety of industries. Universal testing machines equipped with bend fixtures are used to calculate flexural modulus, flexural strength, yield point, and more.

Material Testing in High and Low Temperatures

High or low temperature testing is made feasible by adding an environmental chamber to a universal testing machine (UTM). Environmental chambers come with their own temperature controller and, depending on the system’s compatibility, the temperature settings and recordings may be controlled with the UTM’s controller or software.

Stress-Life Fatigue Testing Basics

ADMET CEO and Chief Engineer Richard Gedney's article on fatigue testing applications was published on the Quality Magazine August 2017 issue. 

The article starts with brief descriptions of the four stages of metal fatigue:

Stage 1: Crack Initiation

Stage 2: : Slip Band or Stage 1 Crack Growth

Stage 3: Stage II Crack Growth

Stage 4: Ductile Failure 

How to upgrade an older Universal Testing Machine?

A Universal Testing Machine Retrofit is a system upgrade in which the capabilities and functionality of an outdated and/or broken universal testing machine are improved by pairing them with advanced indicators and replacement components. A system retrofit is commonly performed on but not limited to tensile testing systems, compression testing systems, torsion testing systems, and bend testing systems. Universal testing systems manufactured by Instron, Satec, MTS, Tinius Olsen, Baldwin, Forney, and others are all capable of being upgraded by ADMET’s retrofit service.

Materials Testing- ADMET Blog

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.

Material Testing Machines

Can anyone guide me how to get crosshead speed range equal to or greater than 1:3000 in a motorized electromechanical material testing machine? The load capacity should remain same even at lowest speed.
