19 Nov 2009: A test method is thereby developed for the mode Ifracture toughness of the lattice. ... Smaller specimens thereby suffice forthe SENB geometry as a fracture toughness test method.

29 May 2009: ound that the Metripol system was unable to identify |sin δ|,and I0/2 directly throughout the tests. ... The values ofsin δ| cycle several times during this test, indicating that multiplerders of birefringence are reached (δ π).

10 Aug 2009: Preliminary electrical tests have shown these microgrippers can beopened by 60–90 at an applied power of,20 mW. ... The prelimi-nary electrical test has shown that they can be opened by60–90 at a power of less than 20 mW.

10 Aug 2009: 3.1. Uniaxial tests on face-sheet materials. The tests on the composite face-sheets were conducted in a screw-driven test machine at a nominal appliedstrain rate of 103 s1. ... The axial strainin both the compression and tension tests was measured by

27 Jul 2009: These experiments are now reported. 3 Experimental InvestigationA series of compressive tests was performed on square honey-. ... 3c. A series of compression tests was performed on the macro-scopic sandwich panels.

10 Aug 2009: Consequently, the face-sheets of the Y-frame sandwich could slide past eachother during the uniaxial compression test. ... A pair of specimens was usedin each double-lap shear test, again using the apparatussketched in Fig.
