DIANA (from DIsplacement ANAlyser) is a Finite Element Analysis (FEA) solution that does basic and advanced analysis of various structures. DIANA FEA BV (previously TNO DIANA BV) develops software and with several re-sellers, distributes it worldwide. A selection of material models, element libraries, and analysis procedures within the package gives DIANA flexibility. Engineers have used DIANA to design dams and dikes, tunnels and analyze underground structures, oil and gas, [1] historical constructions, and large reinforced concrete structures. [2] Some specialized analyses available in DIANA for these fields of use include seismic analysis, [3] fire analysis, and young hardening concrete. [4]

History

In 1972, TNO (Netherlands Organisation for Applied Scientific Research) authored the code that would eventually form the basis of the DIANA FEA BV "DIANA" software. [5] The initial idea had been to develop an in-house code for consultancy work on concrete mechanics and civil engineering. This code was based on the displacement method and was called "DIANA", an acronym for DIsplacement ANAlyser. [6]

In October 2002 the Third DIANA World Conference [7] took place in Tokyo.[ citation needed ]

In 2002, TNO founded TNO DIANA BV to combine commercial and technical activities and to focus on the needs of DIANA users worldwide. Thus, in early 2003, TNO DIANA BV took over technical activities from TNO Building and Construction research, marketing, and sales from DIANA Analysis BV. It also became the owner of Femsys.[ citation needed ]

In 2023, Rocscience made a strategic investment in DIANA.

Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. A properly engineered structure does not necessarily have to be extremely strong or expensive. It has to be properly designed to withstand the seismic effects while sustaining an acceptable level of damage.

Micromechanics is the analysis of composite or heterogeneous materials on the level of the individual constituents that constitute them and their interactions.

<span class="mw-page-title-main">Slope stability analysis</span> Method for analyzing stability of slopes of soil or rock

Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of slopes of soil- and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock. It is performed to assess the safe design of a human-made or natural slopes and the equilibrium conditions. Slope stability is the resistance of inclined surface to failure by sliding or collapsing. The main objectives of slope stability analysis are finding endangered areas, investigation of potential failure mechanisms, determination of the slope sensitivity to different triggering mechanisms, designing of optimal slopes with regard to safety, reliability and economics, and designing possible remedial measures, e.g. barriers and stabilization.

Weakened weak form is used in the formulation of general numerical methods based on meshfree methods and/or finite element method settings. These numerical methods are applicable to solid mechanics as well as fluid dynamics problems.

<span class="mw-page-title-main">VisualFEA</span>

VisualFEA is a finite element analysis software program for Microsoft Windows and Mac OS X. It is developed and distributed by Intuition Software, Inc. of South Korea, and used chiefly for structural and geotechnical analysis. Its strongest point is its intuitive, user-friendly design based on graphical pre- and postprocessing capabilities. It has educational features for teaching and learning structural mechanics, and finite element analysis through graphical simulation. It is widely used in college-level courses related to structural mechanics and finite element methods.

The Sarma method is a method used primarily to assess the stability of soil slopes under seismic conditions. Using appropriate assumptions the method can also be employed for static slope stability analysis. It was proposed by Sarada K. Sarma in the early 1970s as an improvement over the other conventional methods of analysis which had adopted numerous simplifying assumptions.
