The tensile strength of spider silk is greater than the same weight of steel and has much greater elasticity.
À propos de ce matériau
(En anglais seulement) The tensile strength of spider silk is greater than the same weight of steel and has much greater elasticity. It is under investigation for potential applications in industry, including bullet-proof vests and artificial tendons. Researchers have used genetically modified mammals to produce the proteins needed to make this material. Mechanical testing is important to precisely measure the properties of this silk.

FAQ
Qu'est-ce que le module d'Young E?
Propriété mécanique intrinsèque d'un matériau indépendant de sa géométrie. Correspond à la pente du stress par rapport à la contrainte pendant une compression non-confiné lorsqu'on tiens compte de la géométrie de l'échantillon.
Module de laboratoire — Compression non confinée de disques d’hydrogel
Qu'est-ce que l'allongement à la rupture?
La quantité de la déformation uniaxiale à la fracture, y compris la déformation élastique et plastique.
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.

Qu'est-ce que la résistance ultime à la traction (résistance à la traction)?
La résistance ultime est la contrainte maximale développée dans un matériau avant la rupture durant un test de tension.
