3D Normal Indentation Mapping

Mechanical indentation is a rapid and non-destructive assessment technique for biological tissues. Lately, Biomomentum has improved and augmented this technique with both mapping capability and solving...

Tension

The tension test is a fundamental test configuration in the field of material characterization. By pulling on both ends, the goal here is to evaluate how a sample will react to applied loading or displacement...

Unconfined Compression

The unconfined compression test is by far the most popular mechanical testing configuration to measure the mechanical properties of cylindrical-shaped samples. Sample with other geometry can also be tested...

Indentation (Stiffness)

An indentation test is a very convenient way to measure the mechanical properties of a sample non-destructively. Unlike the unconfined compression test, where a sample needs to be harvested from the surface,...

Friction

Friction tests determine the ease of two surfaces to slide against each other when subjected to a contact force. Two main phenomenons are generally observed during these tests: static and kinetic friction....

Bending

Bending (or flexure) tests characterize the behavior of a slender sample (one dimension being a small fraction - a tenth - of the other two) with load applied perpendicular to its longitudinal axis. This...

Torsion

Torsion refers to the twisting of a sample due to an applied torque. Various applications requires materials to withstand torsional stress. It is thus important to test this configuration since material...

3D Thickness Mapping

Using a needle probe under the load cell, it is also possible to map the surface profile and the thickness of a layer of material over a stiffer substrate (e.g. the cartilage layer over a bone). This is...

Shear

Shear tests can be used to evaluate the shear modulus G of a material in planar shear or in torsion. The shear modulus represents the stiffness of a material when a force is applied in a direction parallel...

Simultaneous Compression and Torsion

Simultaneous compression and torsion can be used to determine the mechanical behaviour of specific use samples. This is required in the case where samples primarily undergo complex loading. To accurately...

Dynamic Mechanical Analysis

Dynamic mechanical properties can be assessed from the response of a material subjected to a periodic stimulus which can be applied axially (tension/compression), or in shear (planar or torsion). These...

This test is generally conducted to verify the mechanical resistance of packaging material or packaging seals to internal pressurization. Using Biomomentum's tester, this package pressurization is achieved...

Puncture

Penetration resistance testing involves the insertion of a probe (often a needle or a cone) into a material. Penetration resistance is an important end-use performance reference for thin flexible materials,...

Tack (Adhesive)

It is quite easy to tell when a material is tacky or sticky simply by touching it and feeling how difficult it is to remove it from our fingers. The tackiness is the ability of a material to adhere instantaneously...

Fracture

A complete or partial fracture is the natural conclusion of applying progressively higher amounts of stress to a material. This point could also be referred to as failure. A fracture test is used to find...

Tear

Components often fail in service due to the generation and propagation of a special type of rupture called a tear. The tear test configuration measures the resistance to tearing action on a sample. Resistance...

Push-Out Test

This test configuration is used to evaluate the mechanical stability of a cylindrical plug (bone filler, osteochondral core, cartilage construct) after implantation. After sample preparation (normally...

Peeling (Stripping)

Peeling tests are employed to determine the strength of an adhesive bond between two materials. The peel strength is the average load per width unit required to separate that bond. Using its vertical axis,...

Impact

An impact test is used to quantify the resistance of a sample to high-rate loading. It is very useful in the safety study of product. For this test, an indenter is brought into contact with the sample...

Expression or Aspiration Force

Syringes are tested to quantify the force necessary to activate the plunger and express or aspirate fluid from, or to, the barrel (break-away force, glide force, etc). These forces depend on factors such...

Swelling and Contraction

Swelling and contraction of ionic gels can be induced by various factors such as pH, ionic concentration in the solution, ambient humidity, temperature, ongoing chemical reaction, etc. An easy way to study...

Lap Shear

Like the peel test, the lap shear is important for the mechanical characterization of adhesives. In this test configuration, two layers of material bonded together by an adhesive are forced to slide against...

Indentation (Hardness)

An indentation hardness test is a conventional method of measuring a solid material’s resistance to permanent damage after undergoing a compressive force. Using a very hard pointed indenter with known...

Confined Compression

Confined compression testing measures the capacity of a material to withstand axial compressive loads without expanding perpendicularly to the force. Confined compression tests are usually performed on...

Historically, profilometry was acknowledged as a graph of the surface height as the surface is moved relative to the contact profilometer's stylus (skating on the surface). This notion is changing with...

Profilometry (2D)

Historically, 2D profilometry was acknowledged as a graph of the surface height as the surface is moved relative to the contact profilometer's stylus (skating on the surface) over a line. This notion is...
