Yield strength refers to an indication of maximum stress that can be developed in a material without causing plastic deformation. It is the stress at which a material exhibits a specified permanent deformation and is a practical approximation of the elastic limit. In engineering structural design, yield strength is very important.

Yield strength refers to an indication of maximum stress that can be developed in a material without causing plastic deformation. It is the stress at which a material exhibits a specified permanent deformation and is a practical approximation of the elastic limit. In engineering structural design, yield strength is very important.
The magnitude of the stress at which the transition from elastic to plastic occurs is known as the yield strength. Yield strength is a constant that represents the maximum limit of elastic.
For example, FR-4 plastic fasteners, with a tensile strength of 45,000 psi (310MPa), compare favorably to brass and aluminum fasteners.

FR4, also written as FR-4, is both a name and a standard rating. The name is applied to the fiberglass-reinforced epoxy-laminated sheets used in printed circuit board manufacturing. However, the name also functions as a grade used to rate epoxy laminate sheets. The designation essentially indicates the base quality of a laminate sheet, meaning ..
The figure below, from Mitsubishi Chemical Advanced Materials, shows the test geometry for ASTM D790. ASTM D790 Specimen of 18" x 12" x 5" is placed on two supports and a load is applied at the center. The load at yield is the sample material's flexural strength. The analogous test to measure flexural strength in the ISO system is ISO 178. G-10 is stronger than the other glass-epoxy laminate G-11, but is not as good of an insulator and cant handle quite as high of temperatures. Because of its strength, G-10 is difficult to machine and may require special equipment. G-10FR-4 is available in sheet, rod, and tube. FR-4 is a fire retardant grade of G-10..

In yield point. yield point, a quantity called yield strength is substituted. Yield strength is the stress at which a material has undergone some arbitrarily chosen amount of permanent deformation, often 0.2 percent. A few materials start to yield, or flow plastically, at a fairly well-defined stress (upper yield point) that falls rapidly. Types of Copper and Properties. The copper most commonly used for sheet and strip applications complies with ASTM B370. It consists of 99.9 percent copper, and is available in six tempers designated by ASTM B370 as 060 (soft), H00 (cold rolled), H01 (cold rolled, high yield), H02 (half hard), H03 (three quarter hard), and H04 (hard)..

Take some FR4 PCB material (or thin G10), cut a little oversize and put a screw in the middle . Folks - when you weld 6000 series aluminum (typical boommast extrusions) the yield strength drops significantly. Yield drops from something like 34 ksi to 20 ksi in the welded area. So you think you&x27;re making the boom stronger but you&x27;re locally.
