Analysis of a Beam under Moving Loads

Abstract: It is assumed that a beam made of material has a physical nonlinear behavior. This beam is analyzed under the moving concentrated and distributed continuous loads. The vibration equations of motion are derived from the Hamilton's Principle and Euler–Lagrange Equation. In this study, the amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam has b...

Multiple Moving Cracks in a Nonhomogeneous Orthotropic Strip

The problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. By using the Fourier transform the stress fields are obtained for a functionally graded strip containing a screw dislocation. The stress components reveal the familiar Cauchy singularity at the location of dislocation. The solution is em...

Development of Compact Proton Beam Therapy System for Moving Organs

Masumi Umezawa Futaro Ebina Yusuke Fujii Koji Matsuda Kazuo Hiramoto Kikuo Umegaki, Ph.D. Hiroki Shirato, M.D., Ph.D. OVERVIEW: The use of particle beams in treating cancer, both in Japan and overseas, is growing in recognition of their ability to precisely target the dose of radiation on the cancerous tumor while minimizing the impact on surrounding organs. In particular, it is anticipated tha...

Intensity modulated radiation therapy (IMRT) technique for left breast cancer by different numbers of beam fields

Background: Intensity Modulated Radiotherapy (IMRT) can improve radiotherapy (RT) results by improving healthy tissue sparing. Additionally, IMRT provides more consistent dose deliveries and suppresses secondary tumor formation. RT is a principal treatment in breast cancer (BC). Aim: To evaluate the outcome of the Radiotherapy Plans (RTP) that use IMRT technique to left breast and other organs,...
