The effects of Lorentz′s force Provided by a unstable electromagnetic field with a mechanical field on the stress-strain state of a nonlinear current-carrying thin plate or shell are expounded in this paper The concrete expressions of Lorentz's force in an electromagnetic field have been derived Analyzing the stress-strain state for a ring-shape plate acted by an electromagnetic field with a mechanical fields, the optimum stress-strain state can be determined by the way to change the action of Lorentz's force For designing current-carrying elements or protective components or equipment working in a strong electromagnetic field, this paper is available for reference
