Material Buckling
Materials buckling is the buckling of a homogeneous configuration with respect to material properties only. If we redefine in terms of purely material properties (and assume the fundamental mode), we have:
.
As stated previously, the geometric buckling is defined as:
.
Solving for k (in the fundamental mode),
;
thus,
.
Assuming the reactor is in a critical state (k = 1),
.
This expression is in purely material properties; therefore, this is called the materials buckling:
.

Famous quotes containing the word material:
“Science has done great things for us; it has also pushed us hopelessly back. For, not content with filling its own place, it has tried to supersede everything else. It has challenged the super-eminence of religion; it has turned all philosophy out of doors except that which clings to its skirts; it has thrown contempt on all learning that does not depend on it; and it has bribed the skeptics by giving us immense material comforts.”
—Katharine Fullerton Gerould (1879–1944)
