A web-based tool for the interactive visualization of stresses in an infinite plate with an elliptical hole under simple tension: We present a web-based software tool for the interactive visualization of stresses around an elliptical hole in an infinite plate under simple tension (url{}). The analytical solution of this fundamental problem dates back more than 100 years and has served as a vital contribution in many disciplines of solid mechanics ever since. The presented software provides insight into this important problem by instantly rendering the analytical solution for immediate changes of the dimensions and orientation of the hole, and by allowing the user to zoom closer into regions of interest. The application is openly accessible from modern mobile and desktop devices for the use in education and research and may provide benchmark solutions for numerical methods.
