Used the gauss body heat source to irradiate underwater aluminum target material, in this paper, simulated the process of punching, gauss body heat source equations as follows: (1) Where U is energy on the surface of the aluminum material; a is the optical depth of material; b is the absorptions of material for laser energy; r is 95% of the heat source center to spot radius.
Governing equation of the model can be expressed as a function of temperature: (2) Where is the density of material; is the heat capacity of materials; is time; is the heat source; is changing with temperature coefficient of thermal conductivity.

With the increase of the pad width, more raw materials and the manufacture and operation costs are needed.
Compared with the case study 1, materials somewhat extend on both sides due to the lateral force.
There are still some materials in the middle, but the materials are less than that in case study 1.
(3) When stretching in case study 3, the distribution of materials is exhibiting the V-shape.

Two substrate materials are Sapphire substrate and Silicon substrate.
(5) The materials of all arriving orders are issued first come first in but limited by 2000K grains per day
(6) The materials are successively issued until 100 days and this experiment ends when all orders are completed
