In this paper, the finite-element formulation based on the flow theory of MSG plasticity for pressure-sensitive materials is set up.
Lu Feng et al. [8] presented a mechanism-based stain gradient plasticity theory for pressure sensitive materials with a variable material length-scale parameter based on the Drucker–Prager yield function.
In this work, a finite element format based on the flow theory of the MSG plasticity for pressure-sensitive materials is established.
Then the elastoplastic model should be established to analyse the dimension relativity of the pressure-sensitive materials.

Introduction Manufacturing is the process of converting raw materials, components, or parts into finished products through various techniques, tools and machinery.
The selection of materials for manufacturing is a critical aspect that directly impacts the performance, quality and cost of the final product.
The choice of materials depends on several factors, including the product's intended use, desired properties, manufacturing process and economic considerations.

The IPC of this kind are of interest of not only water-soluble polymers physical chemistry, but also to related fields of science.
Interest in using these materials for biomedical purposes has already been established, particularly in drug delivery systems [10-12].
