Properties of Materials -- Group C by Veronica Pruim https://padlet.com/iv_stavila_pruim/t34erx9wdap4 Describe 5 properties: 1. density 2. strength 3. ductility 4. stiffness / elastic moduli 5. toughness. Include a picture, a definition and the Dutch translation. An example / video is a nice addition. en-us 2017-08-22 09:27:53 UTC 2023-09-11 06:45:44 UTC hello@padlet.com Yield strength https://padlet.com/iv_stavila_pruim/t34erx9wdap4/wish/2680978542 Ramon

In het Nederlands:
Dichtheid
Density defines the amount of mass per volume in kg/m^3.

In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion

Dutch translation: taaiheid

English definition: Toughness is how good of a job a material does at resisting fracturing when force is applied to it.

Dutch translation: stijfheid

Definition: Stiffness is a mechanical property that is a measurement of how much a material can withstand deformation when force or a load is applied upon it.

Ductility is a material property that determines how a material responds to deformation. High ductility materials can undergo extensive plastic deformation before failure and are ideal for applications where flexibility and shaping are important. In contrast, low ductility materials are more brittle and prone to fracture, making them suitable for applications where stiffness and resistance to deformation are essential.

Dutch translation: Lassen

The fabrication process welding is a technique in which two or more components are melded together through the application of heat, pressure, or a combination of both, creating a connection as the components cool down. Although most commonly used on metals, welding is also possible on other materials such as thermoplastics and even wood.

Unlike in other fabrication processes for example soldering, welding melts
 the base material. A weld pool of molten material is formed when high temperatures are applied, which then cools to create a joint, potentially possessing greater strength than the parent metal. Welding can also be accomplished using pressure, either in conjunction with heat or independently.
