The first mode consists of a macroscopic localization, usually linked&nbsp;&nbsp;to the softening effect of void nucleation and growth, in either a normal band or a shear band where the thickness of the band is com-&nbsp; parable to void spacing. The second mode is coalescence with plastic strain localizing to the ligaments between voids by an internal&nbsp;necking process. In this presentation, first, recently developed micromechanics based void coalescence criteria will be reviewed.&nbsp;Then, the question that whether macroscopic localization occurs prior to void coalescence or whether the two occur simultaneously&nbsp;will be addressed.</span></p>\n<p style="text-align: justify;"><span> Danish pastry, coffee and tea will be served 15 minutes before the seminar starts.<br>\n&nbsp;&nbsp;</span><br>\nAll interested persons are invited</p>
