From the engineering perspective, for the sake of meeting the design requirements (bandwidth and absorption rate), issues need to be addressed are: material selection including electrical measuring parameters and geometrical thickness.
Therefore, the optimization results in a wide range of angles and bandwidth for the reflection coefficient are very low, which meets the engineering requirements.
It meets the engineering requirements.

A motivation is to move explosives safety from empiricism to an advanced computation based analytic scientific and engineering basis, facilitating innovation.
Therefore, the practice of explosives design (engineering formulation) is “historically rooted in test protocols used in the qualification of the material that address its performance as well as safety and handling characteristics.” [6].
They appear as expanded internal variables to include sub-scale physics in engineering scale calculations.
The principal focus of the model is shock or impact induced reactive flow processes from initiation to detonation for large scale engineering calculations.
Modified burn models to describe the collective essence of microscopic events, but simple enough for large scale engineering calculations [21].

On the basis of these wave data mentioned above, engineering stress-strain curve of the sample material can be achieved.
After the engineering stress-strain curve was achieved, on the basis of the Eq.2 & Eq.3, Cauchy stress-strain curve can be achieved (Cauchy stress is also called true stress)

GRC is widely used in construction engineering.
However, the durability of GRC is still a major problem in engineering applications, especially GRC materials have been in the hot and humid building engineering environment for a long time.
It is widely used in the construction engineering industry.
It mainly includes civil engineering, municipal engineering, agricultural engineering, fishery engineering, water conservancy engineering and environmental art, etc [1].
