Energy Methods

אנרגיית מעוות
אנרגיית מעוות
Strain energy is a fundamental concept in the field of materials science and structural engineering, describing the energy absorbed by a material or ...
צפיפות אנרגיית מעוות
צפיפות אנרגיית מעוות
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 ...
אנרגיית מעוות אלסטית למאמצים נורמליים
אנרגיית מעוות אלסטית למאמצים נורמליים
When a material is subjected to an axial loading, it experiences normal stress, leading to strain energy generation. This equation is valid for uniformly ...
אנרגיית מעוות אלסטי למאמצי גזירה
אנרגיית מעוות אלסטי למאמצי גזירה
When the material is subjected to a shearing stress, the strain energy density can be expressed in integral form as the product of the shearing stress and ...
עומס אימפקט
עומס אימפקט
Consider a rod of uniform cross-sectional area fixed at one end. When another moving object hits the free end of the rod, the rod deforms, and stress is ...
עומס פגיעה על קורה זיזית
עומס פגיעה על קורה זיזית
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, ...
חוק קסטיליאנו
חוק קסטיליאנו
Castigliano's theorem is useful for determining displacements and rotations in structures undergoing elastic deformations. It states that the partial ...
חוק קסטיליאנו: פתרון בעיות
חוק קסטיליאנו: פתרון בעיות
Consider a simply supported beam PQ of length L, carrying a point load F at the center. What will be the deflection at the center of the beam? Here, the ...
