basic concepts of finite elements, with applications to problems confronted by mechanical designers. linear static, modal, and thermal formulations; nonlinear and dynamic formulations. students implement simple element formulations. application of a commercial finite element code in analyzing design problems. issues: solution methods, modeling techniques features of various commercial codes, basic problem definition. Individual projects focus on the interplay of analysis and testing in product design and development. prerequisite: math103, or equivalent. recommended: me80, or equivalent in structural and/or solid mechanics; some exposure to principles of heat transfer.

although the basic concepts of continuum mechanics have been established more than five decades ago, the 21 century faces many new and exciting potential applications of continuum mechanics that go way beyond the standard classical theory. when applying continuum mechanics to these challenging new phenomena, it is important to understand the main three ingredients of continuum mechanics: the kinematic equations, the balance equations and the constitutive equations. after a brief repetition of the relevant equations in tensor algebra and analysis, this class will introduce the basic concepts of finite deformation kinematics. within the framework of large deformations, we will then discuss the balance equations for mass, momentum, moment of momentum, energy and entropy. while all these equations are general and valid for any kind of material, the last set of equations, the constitutive equations, specifies particular subclasses of materials. in particular, we will focus on isotropic and anisotropic hyperelasticity and on viscoelasticity and elastodamage. finally, we will briefly address variational principles that characterize the governing equations.
