7. The apparatus as recited in claim 6, wherein the first and second members are mechanically connected such that the second member hinders deformation of the first member.

8. The apparatus as recited in claim 7, wherein the first member has two stable positions, the first stable position being where the first member mid-point is adjacent to the second member mid-point, the second stable position being where the first member mid-point is displaced from the second member mid-point to form a gap between the first member mid-point and the second member mid-point.

9. The apparatus as recited in claim 6, wherein the second member has a greater thickness than the first member.

10. The apparatus as recited in claim 6, wherein the thickness ratio of the second member to the first member is greater than approximately 3:

1.

11. The apparatus as recited in claim 6, wherein the thickness ratio of the second member to the first member is greater than approximately 6:

1.

12. The apparatus as recited in claim 4, wherein the bistable device further comprises a wrapping attached to the outer surface of the bistable device.

13. The apparatus as recited in claim 12, wherein the wrapping comprises an expandable screen.

15. The apparatus as recited in claim 14, wherein the deformable material comprises an elastomer.

16. The apparatus as recited in claim 15, wherein the elastomer is selected to be resistant to crude oils, brines, and acids encountered in oil and gas wells.

17. The apparatus as recited in claim 4, wherein the bistable device in its second generally tubular configuration comprises a plurality of diameters.

19. The method as recited in claim 18, further comprising attaching a wrapping to the outer surface of the bistable device.

20. The method as recited in claim 19, wherein attaching comprises attaching an expandable screen.

21. The method as recited in claim 18, further comprising applying a deformable material to the outer surface of the bistable device.

22. The method as recited in claim 21, wherein applying comprises applying an elastomeric material.

23. The method as recited in claim 18, wherein radially expanding comprises expanding the bistable device to a plurality of final diameters.

25. The method as recited in claim 24, further comprising locating multiple bistable devices in the wellbore such that the ends of the adjacent bistable devices overlap and form a continuation of the liner element against the inner diameter of the tubular.

26. The method as recited in claim 24, further comprising creating each bistable cell with a thin strut connected to a thick strut.

30. The method as recited in claim 29, further comprising attaching a wrapping to an outer surface of the bistable member.

31. The method as recited claim 30, wherein attaching comprises attaching an expandable screen.

18. A method of stabilizing an uncased section of a wellbore in an underground formation, comprising:

providing an expandable bistable device having a generally tubular shape that comprises a plurality of bistable cells;

placing the bistable device at a position in the wellbore while in a first stable state; and

radially expanding the bistable device to a second stable state having a generally tubular configuration without substantially reducing axial length.

24. A method for installing liners within a tubular located in a wellbore, comprising:

forming an expandable bistable device with a plurality of bistable cells, the expandable bistable device having a generally tubular shape;

surrounding the expandable bistable device with an expandable liner element attached to an outer surface of the bistable device;

placing the expandable bistable device at a position within a tubular while in a first stable state; and

expanding the expandable bistable device into a second stable state to hold the liner element against an inner diameter of the tubular.

29. A method for facilitating use of a wellbore, comprising:

inhibiting sand influx into a wellbore, wherein inhibiting comprises;

placing a bistable device at a desired position in a wellbore; and

expanding the bistable device at least partially through a nonstable range towards a stable state until the bistable device is able to exert hoop stress forces against the wellbore.

32. A method of facilitating use of a wellbore, comprising:
