Reconfigurable structures that are enabled through the integration of multiple materials are important for future design and manufacturing practice. We investigate one of such reconfigurable structures an origami sheet, which can be designed based on a 3D object and unfolded into a 2D sheet with complex creases. A fabrication approach based on a hybrid manufacturing process by integrating layer...

Hygroscopic swelling characteristics of different types of molding comp ounds and electrical parameters of voltage reference microcircuits encapsulated in plastics were measured after saturation with moisture at 85 C and humidity varying from 20% to 90% RH. Sorption of moisture at high humidity conditions and desorption during baking resulted in deformation of molding compounds of approximately...

According to the special requirements of Sheet Molding Compound (SMC) a set of quadrangular leveling system is designed, whose leveling precision is controlled by electro-hydraulic proportional technology. Based on analyzing the components and working principle of the quadrangular leveling system, the mathematical model of this system is established. The dynamic characteristics of stability and...

The main purpose of bumper is to absorb shock in case of a collision. Several materials have been used to develop these shock-absorbing capabilities, such as steel, aluminium, glass mat thermoplastics and sheet molding compound. The purpose of this project is to design a bumper which is to improve crashworthiness of the bumper beam. Crashworthiness is the ability of the bumper beam to prevent o...

Clinicians have been aware that posterior dental particulate-filled composites (PFCs) have many placement disadvantages and indeed fail clinically at an average rate faster than amalgam alloys. Secondary caries is most commonly identified as the chief failure mechanism for both dental PFCs and amalgam. In terms of a solution, fiber-reinforced composites (FRCs) above critical length (Lc) can pro...
