The material of tool is use Din-D5-1U, which is also a pre stored in the Deform 3D material database.
The material is easily yielded due to the shear deformation of workpiece.
Due to the material of workpiece is constrained by the material around the tool, the plastic flow near the pin needs larger effective stress to be yielded.

Moreover, the new failure assessment curve could be used for any stress-strain relationship material, including Ramborg-Osgood(R-O) material and non-R-O materials under monotonic increasing loading, such as long plastic yield plateau steel.
It shows that Eq. 6 can be used for non-R-O materials under monotonic increasing loading too.

Abstract: The fabrication of low cost ceramic membranes for microfiltration were studied by using a natural materials (shirasu balloon) which are produced from glassy volcanic materials.
Fine shirasu balloons are produce from glassy volcanic materials called shirasu.

Introduction Geopolymer cement is produced by mixing materials that contain aluminosilicate (also called precursor materials), such as fly ash, slag, laterite and other natural or by-product materials, with either an alkaline solution (NaOH, Na2SiO3, and K2SiO3) or an acidic solution (H3PO4).
Moreover, the alkali-to- precursor material ratio was found to be in the range of 0.4 to 0.6 [12, 13] There is little research on geopolymer mortar produced from naturally occurring materials such as laterite soil.
Furthermore, using natural materials like laterite soils to produce geopolymer mortar can provide advantages to rural areas in developing nations by allowing the production of construction materials at the construction site.
