One of the important performances of polyethylene cable jacket materials is environmental stress-crack resistance, while general-purpose LDPE resin cannot meet all kinds of demands.

Now, researchers have taken a crack at understanding this connection by looking for differences in how the brains of people from urban and rural environments react to certain kinds of stress.

Then, combining with microscopic observation of rock specimen sections under compressive loads, the phenomena of stress crack and the dynamic branch have been analysed and discussed.
