Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. Stress analysis may be performed through classical mathematical techniques, analytic mathematical modelling or computational simulation, experimental testing, or a combination of methods.

  • Analisi delle sollecitazioni o analisi delle tensioni (in inglese, stress analysis) è una disciplina ingegneristica che valuta lo stato tensionale in materiali e strutture soggetti a forze o carichi applicati in modo statico o dinamico (in sistemi statici lineari, l'analisi può essere equivalentemente mirata alla determinazione delle deformazioni al posto delle tensioni). (it)
  • Análise de tensões e deformações ou análise de solicitações é uma disciplina da engenharia que avalia o estado de tensões em materiais e estruturas sujeitas à forças ou cargas aplicadas estática ou dinamicamente (em sistemas estáticos lineares, a análise pode ter objetivo equivalente em determinar as deformações em vez das tensões).

  • تحليل الإجهادات (أو تحليل الإجهاد والانفعال) هو تخصص هندسي يستخدم طرقًا عديدة لتحديد الإجهادات والانفعالات في المواد والهياكل المُعرّضَة للقوى. في الميكانيكا الاستمرارية، يُعرف الإجهاد بأنه كمية مادية تعبر عن القوى الداخلية التي تؤثر بها جسيمات المواد المستمرة المجاورة على بعضها البعض، ويُعرف الانفعال بأنه قياس تشوه المادة. في الهندسة، غالبًا ما يكون تحليل الإجهاد أداة وليس غاية بحد ذاتها؛ إذ يتمثل الهدف الأساسي بتصميم الهياكل والمصنوعات التي يمكنها تحمل حمل محدد، باستخدام الحد الأدنى من المواد أو التي تفي بمعيار آخر من معايير المثالية.

  • Festigkeitsberechnungen gehören in das Teilgebiet der Festigkeitslehre (innerhalb der Technischen Mechanik) und werden an * einfachen Probekörpern (z. B. Stäben), * Balken, * Stabtragwerken, * Fachwerken, * Platten, * Membranen aber auch * komplexen mechanischen Konstruktionen durchgeführt. Festigkeitsberechnungen sollen stark und schwach beanspruchte Teile einer Konstruktion identifizieren helfen und führen damit zur Optimierung von Bauteilen. Gleichzeitig dienen sie als rechnerischer Nachweis der Sicherheit einer Konstruktion. Als Methode für Festigkeitsberechnungen eignen sich: (de)
  • Bealaí chun an strus taobh istigh de struchtúr a réamhinsint is a mhonatóiriú. Is é an toradh ar strus ná díchumadh an ábhair atá faoi strus. Tá dhá phríomhshaghas struis ann: strus normálta nó díreach (teannas trí tharraingt nó comhbhrú trí bhrú), agus strus fiartha ar strus i leataobh é. Comhchruinníonn strus ag pointí mar a n-athraíonn cruth an ábhair, agus de réir mar a ghéaraíonn an t-athrú is amhlaidh a mhéadaíonn an strus. Is féidir feidhm a bhaint as ríomhaire chun na struis i struchtúr faoi ualaigh phraiticiúla éagsúla a ríomh. Is bealach é strusanailís fhótaileaisteach chun na struis a dhéanamh infheicthe. Déantar mionsamhail phlaisteach thrédhearcach den struchtúr atá le tástáil. Cuirtear ualaigh (fórsaí) chuí i bhfeidhm ar an struchtúr, agus breathnaítear air trí scagairí polar (ga)
