jäykkäjoustoisia
jäykkäjoustoisia refers to a Finnish term that describes a property of materials or structures. It translates roughly to "rigid-flexible" or "stiff-flexible." This concept is applied in various fields, including engineering and materials science, to characterize objects that exhibit both stiffness and flexibility simultaneously. A jäykkäjoustoisia object is not entirely rigid, as it can deform under load, but it also possesses a significant degree of stiffness that resists excessive deformation. Conversely, it is not purely flexible, as it will return to its original shape to some extent after the load is removed.
The behavior of a jäykkäjoustoisia system is often described by a combination of elastic and plastic properties.
