"rigid bed" is a correct and usable phrase in written English.
You could use it to describe a bed that is made of a sturdy, fixed material that does not conform to the shape of the person who lies in it. For example: "The guest's rigid bed was so uncomfortable that he had a hard time getting a good night's sleep."
We used this model in the erodible and rigid bed.
Thus, the shear stress on rigid bed can be derived from the constitutive equation.
This study successfully performed 2D two-layer shallow water computations on a rigid bed.
Subsequent glacier advance during the Younger Dryas did little to modify the area, suggesting that ice flow was dominated by sliding on a meltwater-lubricated rigid bed, with deformation of basal sediments playing a more limited role.
The second test aims to compare the results of our numerical method to those predicted by an augmented Lagrangian formulation in the case of the collapse and spreading of a granular column over a horizontal rigid bed.
A shallow basin rigid bed physical model, equipped with random sea wave generating facilities from three directions, has been used to study the directional spreading of waves in the model from the wave generating point to different points of interest within the model.
Based on these results, and the presence of ribbed moraines, we suggest a bedform continuum model for onset zones of palaeo-ice streams on rigid beds.
A numerical procedure is presented for solving the equations of Stokes flow past a fixed bed of rigid particles and the equations describing the motion of a suspension of rigid particles upon which a specified force and torque is exerted, for general flow configurations and arbitrary particle shapes.
Results from experiments designed to study ice sliding over a rigid wavy bed, shear deformation of till, and plowing of clasts across the surface of a till bed point to a common conclusion: drag at the bed can decrease with increasing slip velocity, thereby concentrating driving stress elsewhere and promoting rapid glacier flow.
For our purpose, we modified this method by measuring the distance between the patient's heels while the patient lies supine on a rigid orthopedic bed with both knees extended and the examiner passively extends both knees in sequence.
The problems and challenges involved in in situ measurement of dynamic mechanical properties of non-rigid mud bed under water wave pressure have been investigated.
