1 Chapter 4 Shear Forces and Bending Moments 4.1 Introduction Consider a beam subjected to transverse loads as shown in figure, the deflections occur in the plane same as the loading plane, is called the plane of bending. In this chapter we discuss shear forces and bending moments in beams related to the loads. 4.2 Types of Beams, Loads, and Reactions Type of beams a. simply supported beam (simple beam) b. cantilever beam (fixed end beam) c. beam with an overhang 2 Type of loads

to the top, and shear test is by applying a horizontal force to the W. Purposes for this project are listed here. We are using 3D FEM to simulate the stresses experienced by the ball bond during pull and shear testing. We want to examine the stress locations and magnitudes, and see what a bond might experience as we change the wire material, pull angle, bond pad metallization, pad Al thickness, and circuitry under pad. 3. The Bond Pull Strength test typically follows a Mil standard, 883G

Through Silicon-Via (TSV) Technology Abstract Increasing demands for electronic devices with superior performance and functionality with longer battery life while reducing their sizes, weights and energy consumption has driven the semiconductor industry to develop more advanced packaging technologies. Among all different types of packaging technologies proposed, three-dimensional (3D) vertical integration (3D stacking of chips) using through silicon via (TSV) copper interconnect is currently

conditions.The reason why it is important to clear pollutants from the body as fast as possible is because the faster the chemicals are excreted, the less likely they are to have a lasting effect. Long term exposure to pollutants may lead to oxidative stress and a breakdown in the body’s own immune system. This could lead to conditions such as Chronic Fatigue Syndrome (CFS) and liver failure. Combined treatment using detoxification and other treatments can help a variety of chronic conditions. Tips
