HTB-ES Consulting Engineers performed the design and analysis of elevated temperature / pressure vessels. One particular vessel had to operate under a no-leak condition. The challenge was to attach the hemispherical head to the shell without causing distortions, because of temperature differences. We thus designed a series of clamps to seal the two pieces together.
Our expertise includes equipment operating in vibration and elevated temperature environments. We have taken on challenges in a spectrum of industries including energy, aerospace, mining, transportation, materials handling, and manufacturing.

FE Analysis

The finite element analysis (FEA) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as integral equations. FEA client requirements lend themselves for precise definition and ease of sub-contracting. A company planning to obtain Computer Aided Engineering for software or hardware development, may find the cost prohibitive. Therefore the companies in a competitive market traditionally outsource FEA projects.

At HTB-ES , through its experienced team using major FEA Software, provides high end FEA Solutions related to:

  • FE Modeling
  • Linear Analysis
  • Non Linear Static Analysis
  • Dynamic Analysis
  • Transient Analysis
  • Crash Analysis
  • Fatigue Analysis
  • Computational Fluid Dynamics (CFD)

We provide design and thermal, stress, fatigue, finite element, and failure analysis of structures in aerospace applications. This work includes elevated temperature design and analysis to determine structural integrity, limiting operating conditions, and fatigue design life. We also perform structural dynamic analyses to predict loads and responses to environments including transient, random, and acoustic excitation.

  • Vibration analysis of the Hubble Space Telescope
  • Structural life prediction of rocket thrust chambers
  • Creep tensile instability analyses

We perform structural optimization, minimizing component weight, resulting in low materials cost and maximum performance.

We perform thermal, stress, vibration and fatigue finite element analysis (FEA) to accurately model products and processes to ensure structural integrity, performance and reliability. The bottom-line benefits to FEA analysis are: quantifying design cycles, keeping production costs low through design optimization, and uncovering potential sources of field failures.

Failure analysis is a critical aspect of product development and component/system improvement. HTB-ES Consulting performs failure analysis by combining materials and metallurgy with finite element analysis, to determine the precise root cause and developing solutions to ensure structural integrity.
Production line or other heavy machinery failures can be very costly or even catastrophic for a business – we save you time and money by resolving corrosion, vibration, fatigue, or other structural issues.
We have provided solutions on equipment in numerous applications including energy, oil/gas, mining, transportation, aerospace and manufacturing.

  • Pipelines, pumps, valves and compressors
  • Machinery, lift trucks, hydraulic presses, cranes, welded assemblies
  • Pressure vessels, reactors, dryers, and autoclaves
  • Heat Exchangers
  • Boilers, burners, and furnaces
  • Shafts, gears, bearings

We determine how materials and products fail, including mechanical integrity of equipment that has deteriorated due to corrosion, fatigue, damage, abuse, and improper manufacture.

Root Cause Failure Analysis

Components not meeting their intended design life, or accidents and failures often result from factors including:

  • Design errors
  • Material imperfections
  • Manufacturing issues
  • Welding issues
  • Improper heat treatments
  • Misuse or abuse
  • Improper maintenance
  • Unforeseen operating conditions
  • Inadequate quality assurance
  • Inadequate environmental controls

In elevated temperature applications, complicated failure modes may occur, such as creep ratcheting, rupture, and creep fatigue. We have the expertise, technology, and experience to identify and quantify these failure modes - helping you understand the root cause and developing solutions to prevent costly recurrences, thus lowering operating costs and improving safety.

Vibration Analysis

We perform vibration analysis to ensure structural integrity – which may involve determining the design life of structures, or determining how a component may have failed. Most physical systems vibrate – inherent vibration modes in structures can shorten equipment life, and cause premature failure. Often, these failures are catastrophic.

We have performed:

  • Vibration and shock analysis of nuclear equipment in land-based and shipboard applications
  • Seismic analysis of tanks, vessels, skids and welded structures
  • Vibration analysis and repair of equipment including compressors, shafts, piping, and money shredding machines

When a physical system vibrates, it does so at particular natural frequencies – these frequencies and resulting mode shapes can be determined using Modal Analysis. Often, simple modal analysis can be performed, while for more complex systems, finite element analysis is performed to determine to determine the dynamic response. We perform vibration analysis on fans, shafts, pumps, medical equipment, electronic components, and structural support systems, among other components – identifying operating problems and preparing recommendations regarding operating procedure modifications. (If the deletion or addition of a support would chase a vibration problem to another location in the system, we would know it in advance of making the change).
