"flexible foundation" is correct and usable in written English.
You can use it when you are referring to a base or underlying structure that is malleable or adjustable. For example, "The company has a flexible foundation that allows it to change and improve quickly."
A flexible foundation model is also estimated.
In practice the foundation slab is somewhere between rigid and flexible foundation.
For this purpose, a generic monopile based offshore wind turbine with flexible foundation model was used.
Dynamical interactions between equipment, nonlinear isolator, flexible foundation and water waves are addressed.
Drupal itself is a powerful and flexible foundation, but much of its power comes from addons (called "modules" in Drupal parlance).
In this work, the nonlinear dynamic behaviour of a vertical rigid rotor interacting with a flexible foundation by means of two passive magnetic bearings is quantified and evaluated.
A new method is developed for analysis of flexible foundations (beams) on spatially random elastic soil.
This paper presents a comparison of the failure behaviour of the Deep Mixing (DM) method under models of rigid and flexible foundations.
Application of the proposed techniques is illustrated through the examples of homogeneous and composite axisymmetric tower water systems with rigid and flexible foundations.
Moreover, the effect of soil structure interaction (SSI) on TLCD performance is examined, in which the finite and semi-infinite soil flexible foundations are simulated through a finite element model with 1160 DOFs embedding fixed and artificial boundaries, respectively.
This paper presents a structural model for an unloaded tyre, based on a three-dimensional flexible ring on an elastic foundation.
