The phrase "assumed to extend" is correct and usable in written English.
It can be used in contexts where you are discussing an expectation or belief about the duration or scope of something.
Example: "The project's timeline is assumed to extend beyond the initial deadline due to unforeseen circumstances."
Alternatives: "expected to last" or "believed to continue".
The soil suction variation in the active zone was assumed to extend to the whole active depth.
They also assume that damping continuously increases with amplitude, or that it reaches a maximum value that is assumed to extend to wind-resistant design amplitude levels.
Faults are assumed to extend to a depth of 5 10 km, below which they creep at the full relative plate velocity.
The magnetic configuration of the long leg divertor is obtained by EFIT and Tokamak Simulation Code (TSC), while a hypothetical geometry is assumed to extend the out divertor leg as long as possible inside vacuum vessel.
The medium on the entrance side was assumed to be either air or water, and the NOA-61 on the exit side could be assumed to extend to infinity because its thickness is several tens of micrometers.
Dislocations are assumed to extend at least throughout half the cross section of a fiber, which is a reasonable assumption since large dislocations are known to extend all the way across a fiber (Forgacs 1961; Nyholm et al. 2001).
The BM, however, is assumed only to extend from element 2 to element N − 1. Element 1 is used to account for the effect of the stapes velocity, shown as u s in Figure 9.
The fluid is assumed to be infinitely extending having the free horizontal surface in the x y plane.
The samples up to time k are also assumed to be generated by extending the samples of the path up to time k−1.
The generatrix of a cone is assumed to be infinite in length, extending in both directions from the vertex.
In Section 4, we extend Theorem 1.3 by assuming to be only l.s.c., and extend Theorem 1.4 to multivalued mappings.
