numerical method for solving physical or engineering problems

thumb|Buckled skin panels on a Boeing B-52 Stratofortress|B-52 aircraft. Thin skin panels buckle at very low loads. In the case shown here, the weight of the forward fuselage structure ahead of the nose undercarriage is sufficient to cause the panels to buckle. Buckled panels are still effective in carrying shear by diagonal tension. thumb|On the front of a new Siemens Venture railway coach made of stainless steel, unevenness caused by buckling becomes apparent because of the reflection on the polished surface.
