Beams
Browser based Euler beam models for statics, normal modes, dynamic response to a dropped weight and a beam section optimizer. A full selection of boundary conditions and load types.
Tip:
Documentation PDFs include solution methodology, assumptions and references.
Beam
Static Beam
Deflections and stresses can be determined for a multi-segmented beam with a wide selection of boundary conditions and loads.
Define the number of segments and their respective section properties and loads
Define nodal boundary conditions and loads
The segments and nodal parameters can be changed by clicking on them
Outputs include deflections, shear and moment diagrams and bending stresses
Unique feature: nodes can be zero moment hinges
Beam
Normal Modes
Natural frequencies and mode shapes can be determined for a multi-segmented beam with a wide selection of boundary conditions.
Define the number of segments and their respective section properties
Define nodal boundary conditions and discrete weights
Outputs include the 3 lowest modal frequencies and mode shapes. They can be animated.
Unique feature: concentrated weights can be added to the nodes
Beam
Dropped Weight Response
The segmented beam response to a dropped weight can be determined
Define the number of segments and their respective section properties
Define nodal boundary conditions and discrete weights
Define the dropped weight and drop height
Outputs include the dynamic response deflections versus time. The shape is animated.
Unique feature: the dropped weight can have a user input coefficient of restitution from 1 to 0. If 0 the dropped weight adds to the nodal weight for the response.
Beam
Beam Segment Optimizer
Given a user defined range or specific set of available section properties the optimizer with minimize the sections needed to meet a specified stress criteria.
Define the number of segments and their respective starting section properties
Define the range or specific section properties to be used for the optimization
Define the maximum/minimum stress criteria
Define nodal boundary conditions
Outputs include the optimized segments with their sections and the resulting stresses
Unique feature: a wide section property range can be used to find the unrestrained optimum
Quick selection
Which module should I use?
Static Beam : basic beam analysis results given the user defined beam segment properties and loads and nodal boundary conditions and loads
Beam Modes : given user defined segment properties and nodal boundary condition the lowest 3 natural frequencies and mode shapes can be determined
Beam Response to a dropped weight : with user defined segments and nodal boundary conditions the beam dynamic response can be determined to a dropped weight at a height
Beam Optimizer : given the number of segments and nodal boundary conditions and loads the segment section properties are optimized to a given stress criteria
For safety-critical decisions, validate results independently with further detailed analyses and testing.

These modules implement physics-based, low-order models for rapid engineering insight. They prioritize speed and transparency over high-fidelity FEA and similar simulations. Assumptions, boundary conditions, and correlations used are documented in the PDFs and within the modules. Users are responsible for verifying applicability and results for their specific use case.
