The phrase "a fixed shape" is correct and usable in written English.
It can be used when describing an object or figure that maintains a specific, unchanging form.
Example: "The sculpture was designed to have a fixed shape, ensuring it would not deform over time."
Alternatives: "a stable form" or "a constant shape".
It is shown that for a fixed shape, there exists an optimal volume Vopt for which the adhesive strength has a maximum.
Compared with rival technologies that can be curved into a fixed shape but aren't completely pliable, Royole's displays are as thin as an onion skin and can be rolled tightly around a pen.
A classical thermodynamic analysis reveals that the generalized KV theory enables us to estimate the interface energy of a particle with a fixed shape, even if the shape of the particle is not controlled by minimization of the interface energy.
Unlike some existing analytic methods, in which a fixed shape of the trajectory is assumed, the proposed trajectory model in this paper is based on the initial and target orbit elements, through which the fitting ability for the trajectory shape is effectively improved.
Gases do not have a fixed shape.
The MG and ML distributions have a fixed shape and the scalar parameter varies the width.
For any fixed shape and size of cavities, the maximum stress is shown to be linear with the reciprocal of squared number of cavities.
Neither the contention domain of one node, nor the domain sensed by two nodes simultaneously, is not a region with a fixed area or fixed shape.
We demonstrate, through a series of examples, optimal topology achieved through sequential insertion of a heterogeneity of fixed shape and optimization of its configuration (location, orientation and scale).
To incorporate cell-to-cell variability in Ras levels, we sampled the peak RasGTP values from a gamma distribution whose mean increases with increasing input magnitude (with fixed shape parameter k see Methods).
It is evident from the micrograph that OPA powder was an assemblage of fine particles, which did not have regular fixed shape and size.
