Design consideration for plastic material
WebExamines the mechanical properties of materials (e.g., strength, stiffness, toughness, ductility) and their physical origins. Explores the relationship of the elastic, plastic, and fracture behavior to microscopic structure in metals, ceramics, polymers, and composite materials. Discusses effects of time and temperature on materials properties. … Webthe plastic material. Finely ground powdered plastic has a bulk density factor at least three times greater than the same material molded into a solid part. The distance between two parallel walls must provide enough volume for the powdered plastic, and enough space for the material to flow through the mold and uniformly coat the cavity walls.

WebThis report discusses the influence of the material properties on the structural behaviour of a steel member. In particular, the ability of such a member to redistribute bending moments in the inelastic range is investigated. The investigation was initiated as part of a program to apply plastic design rules to the high strength, low alloy steels.
