There are limited available datasets on building materials as they are typically not transparent, and research is usually done to individual materials or components.
Unfortunately, construction activities consume as much as 40% of global energy and materials used, emitting about 35% of carbon dioxide [20] using 30% raw materials and 28% of landfill material as construction debris [6].
Although less toxic and safer materials such as sustainable and green building materials are available, they are not widely used.

Current Status of New Materials With the constant development of the sweater industry, new materials have become the priority and foremost condition for the creation of sweater products.
New raw materials, such as modal, tencel and fancy yarns, have not only given new concept of science, but also upgraded the intrinsic artistic quality of sweaters by virtue of their unique yarn structure and injected full of vigorousness to enterprise, bring about abundant economic profit.
Influence of Raw Materials on Sweater Products From the perspective of sweater products, the raw material plays as an important role influencing the overall style of the sweater.

As shown in Fig.1, the side length of the 0.1 kg cubic concentrated explosive charge is 0.04 m, with its mesh size 5 mm, and as the blasting center distance increases, the mesh has a very sparse gradient coefficient of two. 73926 nodes and 68688 elements were created in total, and all the materials were divided into Eulerian meshes, which allows multiple materials in one element.
In an Euler solver, the numerical mesh remains undeformed, while several kinds of materials are allowed to flow freely from one element to another.
This solver is suitable for modeling fluid phase materials, such as gas or liquid.
