Material behavior and the concepts of equilibrium and compatibility of deformation. Torsion of bars is discussed with application of problems of shaft design. Stress in beams of simple and composite shapes is considered as well as shear in beams and combined twisting and bending. Deflection of beams, shafts and structures are discussed using several calculation procedures. Stress and strain are considered in 3-dimensions with attention to principal directions. Buckling is considered and some attention is paid to plastic action in the various course topics. Both experimental and numerical laboratories will be conducted on various topics covered in the course.

After reviewing the development of the flexure formula, the stress equation is derived for unsymmetrical bending. Curved beams loaded in the plane of curvature are analyzed as are beams with combined axial and lateral loadings. The general equation for beams on elastic foundations and its applications are studied. Stresses and deflections due to dynamic loads are examined. The basic equations of elasticity are developed and two-dimensional problems analyzed using Airy's stress function. Solutions are compared to strength of materials results. Energy methods are discussed. The Lagrange plate equation is derived and plates fabricated from modern composite materials are discussed.
Modeling of fiber-reinforced composites. Property characterization methods. Elastic and plastic behavior of fiber-reinforced composites. Modes and mechanisms of failure. Analysis of laminar composites. Design of microstructure of polymer-matrix composites and application to structural components.

Dr. Chalivendra obtained his undergraduate degree and masters degree from Sri Venkateswara University College of Engineering, Tirupati, India in 1993 and 1997 respectively. He worked for two different industries: Bharat Electronics Ltd., and Tata Refractories Ltd., for two and half years in India before pursuing his doctoral degree at University of Rhode Island during 2000-2003. His doctoral dissertation is focused on analytical and experimental treatment of fracture studies in functionally graded materials. He developed analytical crack tip field equations for an arbitrarily oriented crack in functionally graded materials under both stationary and transient dynamic loading conditions. As a postdoctoral fellow at California Institute of Technology during 2003-2005, he conducted experimental investigation of well-controlled dynamic fragmentation studies for validation of large-scale simulations. He joined UMASS Dartmouth in 2005 and now serving as Professor in Mechanical Engineering Department. He is also currently serving as Graduate Program Director for the department. He published about 70 peer-reviewed journal articles and currently serving as a Technical Associate Editor for Experimental Mechanics journal. He was awarded about $2M external grant funding for conducting research for understanding materials behavior under various loading conditions at different length scales. He graduated sixteen masters students and one doctoral student from his research lab. He also trained 33 undergraduate students in his research lab and published 12 peer-reviewed articles with them as co-authors. His research interests include, Smart composite material, biological materials, nano-mechanical characterization of MEMs and polymers, high strain rate behavior, and impact characterization of sports helmets.
