Basics of Prototype Sheet Metal Design: An explanation of plastic deformation (cutting and bending) and the fundamentals of material mechanics.
Sheet metal processing refers to the general term for the process of plastically deforming thin sheets at room temperature (cutting and bending) into various shapes. When an external force is applied to the material, it deforms, and depending on how the load is applied, the state of deformation can be classified into five categories: "tension," "compression," "shear," "bending," and "twisting." Among these, sheet metal primarily involves three types of deformation: "drawing (tension and compression)," "shear," and "bending." Understanding the relationship between "material properties" and "applied stress" helps to support the work processes involved in sheet metal phenomena. When considering bending and drawing processing forces, similar to calculating shear processing forces, they are derived based on tensile strength and various factors such as material length and sheet thickness. *For more details, please refer to the PDF document or feel free to contact us.*

basic information
【Tensile Strength】 - The strength inherent to the material, determined through tensile testing. - A reference value during shear and bending (yield point, endurance limit, reference). - (Maximum tensile load) ÷ (original cross-sectional area) = (tensile strength). - Unit: Pa = N/mm². 【Shear Resistance】 - Approximately 80% of the tensile strength value is used as a substitute. - An inherent value of the material. - Used as a guideline for understanding the load during punching processes. - P = L · t · S - P: Shear processing force (N) - L: Processing circumference (mm) - t: Plate thickness (mm) - S: Shear resistance (N/mm²). *For more details, please refer to the PDF document or feel free to contact us.*
