كثافة الطاقة الانفعالية
An axial load causes a rod to elongate, and store strain energy in it. The strain energy density in the rod is the energy per unit volume. Here, the ratio ...
طاقة الانفعال المرنة للإجهادات العادية
طاقة الانفعال المرنة للإجهادات العادية
When a material is subjected to an axial loading, it experiences normal stress, leading to strain energy generation. This equation is valid for uniformly ...

تأثير التحميل على عارضة كابولية
Consider a cantilever beam fixed at one end, having a circular cross-section. If an object is dropped on the free end of the cantilever from a height h, ...
نظرية كاستيجليانو
نظرية كاستيجليانو
Castigliano's theorem is useful for determining displacements and rotations in structures undergoing elastic deformations. It states that the partial ...
