Pseudo-dynamic testing method based on external displacement control Dapeng Wanga, Shizhu Tianb Suzhou University of Science and Technology, 1701 BinheRoad Suzhou 215011, Jiangsu, China awangdapeng@mail.usts.edu.cn, btianshizhu@mail.usts.edu.cn Keywords: external displacement control; closed-loop control; error compensation; PID parameters; pseudo-dynamic testing Abstract: In order to accelerate the velocity and improve the accuracy of the pseudo-dynamic testing, the external displacement control method is put forward based on the hardware control.
The shortcoming of the method is that the lower loading velocity will have some effect on the testing results of some structures with relatively high damping material, especially for the passive energy dissipation.

For example, the event “delayed arrival of construction material” can cause a delay in execution.
Events can affect activities, material or work resources, lags, and calendars in project execution process.

Today, materials with high thermal hardness, high tensile strength, and sufficient thermal conductivity such as powder metallurgy (PM) high-speed steels are more frequently used.
These developments pose challenges to fine machining operations and require further investigation of the process and the cutting materials [2].

The coefficient of friction was measured for SPF aluminium grades AA7475 and AA5083, and steel and alumina based cement tool materials.
Above this threshold, the shear strength of the material offers lower resistance and contact friction is proportional to the flow strength of the material.
