This mineral is hard, and provides compressive strength. Thus, the collagen and mineral together are a composite material with excellent tensile and compressive strength, which can bend under a strain and recover its shape without damage. This is called elastic deformation. Forces that exceed the capacity of bone to behave elastically may cause failure, typically bone fractures.

In addition to its ability to emit light under a strain of greater than 480% its original size, the group's HLEC was shown to be capable of being integrated into a soft robotic system. Three six-layer HLEC panels were bound together to form a crawling soft robot, with the top four layers making up the light-up skin and the bottom two the pneumatic actuators. The discovery could lead to significant advances in health care, transportation, electronic communication and other areas.

He replaced his old straw chair, for example, with an armchair covered in Moroccan leather; his old desk was replaced with an expensive new writing table; his formerly beloved prints were replaced with more costly prints, and so on. "I was absolute master of my old dressing gown", Diderot writes, "but I have become a slave to my new one … Beware of the contamination of sudden wealth. The poor man may take his ease without thinking of appearances, but the rich man is always under a strain".

The superplastic behaviour of Fe-28Al, Fe-28Al-2Ti and Fe-28Al-4Ti alloys has been investigated by tensile testing, optical microscopy and transmission electron microscopy. Tensile tests were performed at 700–900 °C under a strain rate range of about 10−5 to 10−2/s. The maximum strain rate sensitivity index m was found to be 0.5 and the largest elongation reached 620%. In Fe3Al and Fe Al alloys with grain sizes of 100 to 600μm exhibit all deformation characteristics of conventional fine grain size superplastic alloys.

In the late 1990s, the collective farming system collapsed under a strain of droughts. Estimates of deaths due to starvation ranged into the millions, although the government did not allow outside observers to survey the extent of the famine. Aggravating the severity of the famine, the government was accused of diverting international relief supplies to its armed forces. Agriculture in North Korea has suffered tremendously from natural disasters, a lack of fertile land, and government mismanagement, often causing the nation to rely on foreign aid as its primary source of food.

In 1945 US Army Rangers raid the Cabanatuan Japanese prisoner-of-war camp, rescuing its POWs. The film flashes back to March, 1942, and the Bataan peninsula in the Philippines. As U.S. Army troops under General MacArthur struggle to hold on at Bataan against the Japanese, Colonel Joseph Madden (John Wayne) orders one of his officers, Captain Andrés Bonifacio (Anthony Quinn), to shape up. Bonifacio has been under a strain because his sweetheart Dalisay Delgado (Fely Franquelli) is apparently collaborating with the Japanese, broadcasting propaganda over the radio.

Some believed that the marriage between Edith and Woodrow was hasty and controversial. Others did not approve the marriage because they believed that Woodrow and Edith had begun communicating with each other while Woodrow was still married to Ellen Wilson. In 1921, Joe Tumulty (Wilson's chief of staff) wrote: "No public man ever had a more devoted helpmate, and no wife a husband more dependent upon her sympathetic understanding of his problems ... Mrs. Wilson's strong physical constitution, combined with strength of character and purpose, has sustained her under a strain which must have wrecked most women".

This crystal bistability was proved by calculations for LiCuO2 and NaCuO2 crystals, in which the Cu3+ ion has the electronic e2(d8) configuration (similar to the CuF3 molecule). Giant enhancement of observable properties in interaction with external perturbations. In a recent development it was shown that in inorganic crystals with PJTE centers, in which the local distortions are not ordered (before the phase transition to the cooperative phase), the effect of interaction with external perturbations contains an orientational contribution which enhances the observable properties by several orders of magnitude. This was demonstrated on the properties of crystals like paraelectric BaTiO3 in interaction with electric fields (in permittivity and electrostriction), or under a strain gradient (flexoelectricity).
