In engineering, deformation refers to the change in size or shape of an object. Displacements are the absolute change in position of a point on the object. Deflection is the relative change in external displacements on an object. Strain is the relative internal change in shape of an infinitesimally small cube of material and can be expressed as a non-dimensional change in length or angle of distortion of the cube. Strains are related to the forces acting on the cube, which are known as stress, by a stress-strain curve. The relationship between stress and strain is generally linear and reversible up until the yield point and the deformation is elastic. The linear relationship for a material is known as Young's modulus. Above the yield point, some degree of permanent distortion remains after

  • En ingeniería, el término deformación se refiere al cambio de tamaño o forma de un objeto. Los "desplazamientos" son cambios "absolutos" en la posición de un punto del objeto, y las "deflexiones" son cambios "relativos" de los puntos de un objeto con respecto a sus puntos colindantes. (es)
  • 변형은 어떠한 물체를 바꾸거나 그 형태를 달리하는 것이다. 일반적으로 물리적 변형과 화학적 변형으로 나뉘며, 위 두가지는 물체의 구조가 변하였는지의 여부를 기준으로 결정한다. (ko)
  • التشوه في علم المواد، يشير إلى أي تغييرات في شكل أو حجم كائن بسبب: * قوة تطبيقية (يتم نقل طاقة التشوه في هذه الحالة من خلال العمل) أو * تغير في درجة الحرارة (يتم نقل طاقة التشوه في هذه الحالة من خلال الحرارة). الحالة الأولى يمكن أن تكون نتيجة قوى الشد (الشد)، قوى الضغط (الدفع)، القص، الانحناء أو الالتواء (التواء). غالبا ما يوصف التشوه على أنه إجهاد. يمكن تطبيق مفهوم الجسم الصلب إذا كان التشوه لا يكاد يذكر.

  • Dalam ilmu material, deformasi adalah perubahan bentuk atau ukuran dari sebuah objek karena * Sebuah diterapkan gaya (energi deformasi dalam hal ini ditransfer melalui kerja) atau * Perubahan suhu (energi deformasi dalam hal ini ditransfer melalui panas). Kasus pertama dapat menjadi akibat dari kekuatan tarik, kekuatan tekan, , lipatan atau (memutar). Deformasi sering digambarkan sebagai . (in)
  • Deformatie en vervorming verwijzen naar de verandering in grootte of vorm van een materiaal of object in de materiaalkunde en andere takken van engineering. De bepaling van de effecten van mechanische spanning en rek op een vast materiaal of object wordt beschreven door de sterkteleer en voor een constructie door sterkteberekeningen. (nl)
