Sea el cuadrado de la figura sometida a un estado de deformación plana ($\\varepsilon_{13}=\\varepsilon_{23}=\\varepsilon_{33}=0$) homogénea.

\n

\n

De esta deformación se sabe lo siguiente:

\n
\n
• La deformación volumétrica vale $\\varepsilon_v=\\var{epsion_v}$
• \n
• La variación angular del ángulo ADC vale $\\var{delt_12}$ radianes.
• \n
• El alargamiento unitario del lado EC vale $\\varepsilon_{EC}=\\var{eps_chi3}$
• \n
\n
