locking wave cables

[Розмари]

Здравствуйте, помогите, пожалуйста перевести locking wave вот в этом куске из инструкции по испытанию кабелей:Locking Wave Trial
The locking wave comprised a cumulative bend angle of 300°, four half waves of overall length 14.5 m with an offset amplitude of 450 mm. The load was incremented in 120 minute time periods. In the first 60 minutes the load was compressive and in the second 60 minutes was tensile. The trials were performed at 20°C.T
