Example Sentences

"Glass, while strong, is prone to breaking when stress exceeds its tolerance, but interestingly, the movement of atoms and molecules within glass can relax internal stress, making the material more resistant to fractures," points out Makina Saito, an associate professor at Tohoku University's Graduate School of Science.

From Science Daily

This interplay of atomic jumps and collective motion reduces internal stress, protecting the glass from breaking under external force.

From Science Daily

"As ice enters what they call a free drift state, the internal stress becomes negligible, and the external forces of wind and the ocean surface tilt start to dominate. The models suggest that changes in the wind and ocean surface tilt will drive a slowdown of the sea ice during the summer season."

From Science Daily

These covalent linkages serve to disperse internal stress caused by volume expansion during lithium-ion battery operation, alleviating the changes in micro silicon volume and enhancing structural stability.

From Science Daily

Cameo’s unsuccessful lurches into new products and growing internal stress put new scrutiny on Mr. Galanis and his unfocused management style.
