Description

The material type for a multigeneration solid is multigeneration. This material describes a mixture of elastic solids, each created in a specific generation. It is a container for any combination of the elastic materials described.

Repeat the generation property as many times as needed (see generation).

Example:

<material id="1" name="Growing Solid" type="multigeneration">
  <generation id="1">
    <start_time>0.0</start_time>
    <solid type="Holmes-Mow">
      <density>1</density>
      <E>1</E>
      <v>0</v>
      <beta>0.1</beta>
    </solid>
  </generation>
  <generation id="2">
    <start_time>1.0</start_time>
    <solid type="Holmes-Mow">
      <density>1</density>
      <E>1</E>
      <v>0</v>
      <beta>0.1</beta>
    </solid>
  </generation>
</material>

The corresponding value of \(t^{\gamma}\) for each of the generations is provided in the Globals section.

Example:

<Globals>
  <Generations>
    <gen id="1">0.0</gen>
    <gen id="2">1.0</gen>
  </Generations>
