How do I apply a shear load, V, and bending moment, M on a thin-walled cylindrical shell FEM to capture the correct bending stresses and shear stresses according to beam theory? According to beam theory, the bending stress is a function of sine, fb = M*Sin(theta)/(Pi*r^2*t) and the shear stress is a function of cosine, fv = V*Cos(theta)/(Pi*r*t) where theta is the angle above the neutral axis.

As the semiconductor industry races to keep pace with Mooreâ€™s Law, which regards the doubling of transistors per square inch on integrated circuits, lithography hardware systems are not always able to provide a quality image for creating circuits. Download Now
Current integrated circuit (IC) designs are complex, which can result in different voltages being located close to one another. To prevent time dependent dielectric breakdown (TTDB), it is essential to incorporate space rules within IC design. Download Now
