definitions of porosity

google definitions of porosity

• Degree to which soil, gravel, sediment or rock is permeated with pores or cavities through which water or air can move.
• A measure of the number and size of the spaces between each particle in a rock.
• Percentage of the rock volume that can be occupied by oil, gas or water.

aim:
this experiment examines the porosity of a surface created by an explosion. in particular, addressing the cavities, spaces and volumes of porosity as a means of defining form.

hypothesis:
if a surface is exposed to an explosive force it will deform and eventually decompose. if a surface's porosity is measured by the spaces between each particle then the porosity will be at it's greatest at the moment prior to the surfaces dissolution.

method:

1. using small objects a large surface will be created.
   
2. deform the surface with a single explosion.
3. record the surface's actions from the top view, side view and front view.
4. find the moment when the surface reaches it's breaking point.
5. model the surface at break point.
6. repeat using multiple explosions.
