Support d’échantillon, mords pour essais en tension (2 ensembles) et plaque de montage

MA090

Deux paires de mords pour essai en traction et plaque de montage permettant de fixer l’échantillon

UGS : MA090 Catégories: ,

(En anglais seulement) These grips were designed for tension testing of soft sheet material. Their C-shaped cavities, coupled with the screwed stainless steel bar, solidly lock the sample in the grip. This set includes 4 grips (2 sets of 2) and the mounting plate allowing for an easy fixing of the sample.

FAQ

Comment fonctionne le modèle "Sinusoid"?

(En anglais seulement) This feature is used to obtain the Frequency, Amplitude and Offset of a sinusoidal signal. A blue line displays the theoretical sinusoid with the Frequency, Amplitude and Offset obtained (Figure 1). The values of the Frequency, Amplitude and Offset are indicated in the "Results" field. The units vary according to the graph’s axes.

This feature can also be used for sinusoidal stimulus-response analysis. Sinusoidal stimulus shall be selected on the x-axis and the sinusoidal response on the y-axis. The Modulus is the ratio of the response Amplitude over the stimulus Amplitude. The Phase is the phase difference between the response and the stimulus. The Modulus’ is computed as the Modulus*Cos(Phase) and the Modulus” is computed as the Modulus*Sin(Phase). A blue line displays the theoretical sinusoidal stimulus-response with the Frequency, Modulus and Phase obtained (Figure 2). The values of the Modulus and Phase are indicated in the “Results” field. The units vary according to the graph’s axes.

One use for this feature would be to compute material properties by multiplying the Modulus obtained by the appropriate geometric factors. For example, the Young’s Modulus can be obtained during uniaxial compression or tension on cylindrical sample with t/pi*r2 as the geometric factor, t is the thickness and r is the radius of the sample.
