Wind loading and windborne debris (missile) impact are the two primary mechanisms that result in window glazing damage during hurricanes. Wind-borne debris is categorized into two types: small hard missiles; such as roof gravel; and large soft missil

Creep and Stress Relaxation Behavior of Homogeneous and Reinforced Compliant Mechanisms and Segments
Publikováno v:
Volume 5A: 42nd Mechanisms and Robotics Conference.
Two critical disadvantages of compliant mechanisms constructed of engineering plastics are poor creep and stress relaxation resistance. Metallic reinforcement is investigated as a method to improve the creep and stress relaxation behaviors of complia

A method based on the pseudo-rigid-body model (PRBM) is presented for the analysis of stress in metallic-reinforced, small-length flexural pivot (SLFP) compliant segments, subjected to end loads or displacement boundary conditions. The analysis metho

The effects of oxidation on heat transfer and mechanical behavior of ZrB2-SiC ceramics at high temperature are modeled using a micromechanics based finite element model. The model recognizes that when exposed to high temperature in air ZrB2-SiC oxidi

Building facades are vulnerable to wind and wind-borne debris during extreme weather conditions like hurricanes. Laminated glazing is widely used as window glazing material to ensure the integrity of the building interiors. Wind-borne debris has been
