Abstract

Capturing non-linear deformation history of a material such as quartz by solving non-linear equations from the start provides for improved computational simulation of electronic devices during the design stage. In some embodiments, the process includes solving a set of non-linear equations, including a non-linear equation related to a strain characteristic of the material, a non-linear equation related to a first stress characteristic of the material, and a non-linear equation related to a second stress characteristic of the material; updating a value of the strain characteristic; and solving the set of non-linear equations to obtain a further updated value of the strain characteristic, an updated value of the first stress characteristic, and an updated value of the second stress characteristic.
